Nov 15 Classic Box Cost Disappointed in the decision to bundle the subs and (at least for now) not have a separate Classic sub option. That said, can we at least get a separate box cost for access to classic? It would: - help alleviate temporary bloat and subsequent dead realms - servers would be more stable population-wise over time - remove the bulk of the need for sharding - give a solid idea of how many servers will be needed - allow blizzard to set up a separate classic forum for those with a monetary commitment - with a separate forum group, feedback would be limited to those with a vested interest The subs would still be bundled, but there would be a box cost, akin to what one would have to pay for BFA access. A very good to-the-point post from later on in this thread:... Another good post about how the current setup would necessitate sharding:... A decent (albeit short-term) alternative:...Brokenwind314 Nov 15
In this form, there is much less wasted space and spells are no longer limited to three effects. But before we can load any database data, we need to transform the old data layout into the new one. This is not limited to spells, as almost every game system (including items, creatures, player characters, spawning, AI, and more) has had its database layout altered over the years.

World of Warcraft: Classic might be just around the corner, so it’s about time to start preparing. We’ve already published a class selection guide, and today we’re focusing on the most important resource of the game, of course, it is gold. Many players who played World of Warcraft back in the day might remember the times when you needed to count every spent penny and the times when gold farmers roamed the Azeroth on their super expensive epic mounts. In vanilla WoW, gold was everything. And we’re here to help you save as much of it as possible. So, without further due, let’s dive in our World of Warcraft: Classic gold making guide.

I made some route changes to the Horde levels 43-44 sections.  I have swapped 44 Dustwallow Marsh with 44 Desolace (the entire sections). This allowed me to do Deadmire (at lvl 43 instead of 38) and then go stop at TB to turn in Deadmire + The Black Shield at the same time, then fly quickly to do the Desolace stuff.  Doing 44 Desolace is now mandatory because I think its faster with the new routes. This will also make the level 53 grind much shorter.  I think these were great changes.
Fortunately, WoW’s modern editor is able to perform some of these data conversions, and for the terrain data we could convert it with the same editor we used on Battle for Azeroth. The modern editor “knows” how to load the old terrain format and how to transform it into the new terrain format and export it to the modern engine. This corrected the issues of campfire placements and the appearance of trees, among other things.
Nov 15 Managing your time and Classic So how are you guys thinking you're going to do it? I know when I played Vannila, I sunk so much time into it as I didn't have any responsibilites. Nowadays I work 24 on, 48 off (which is actually good, except for raid days) and have a wife. I figure a lot of you will be in the same boat. That may be a good thing as it can slow the pace a bit.Crupzz4 Nov 15
Wait, /sit to trigger crits is p-server thing? I distinctly remember people saying that if you sit, you will be crit when I played 1.12 Vanilla. On top of that - there’s that pally that one shot Kazzak in early Vanilla because he stacked a shitload of reckoning when it didn’t have a limit - it’s not inconceivable that he did it without /sit to trigger crits, but it would take him so, SO long to do that without /sit.
Nov 15 The most hardcore thing you can do. In vanilla? I have a few things that could be it. Playing on a perma death PvP server and kill kel'thuzad. Without dying even once. Being able to kill a mage/rogue/warlock/pally in all BiS gear Soloing a high end dungeon boss like rivendare or dark master gandling. Leveling to 60 with no gear or weapons or pet of any kind. That is by far the most hardcore, life threatening thing you can do in vanilla wowHavell7 Nov 15
Nov 15 I Don't Have Time To Reach Rank 11-14 I Don't Have Time To Reach Rank 11-14 and this is perfectly ACCEPTABLE! I actually like the fact that rank 11-14 is extremely hard to get and time consuming. I don't care if it's not about skill, it is very RPG feeling in the fact that, the people who put in the most time and effort spilling the most enemy blood are the ones who get the best rewards. as somebody who will NEVER have a chance of getting those ranks and items because; 1. I do not have time to do it 2. even if I did have time I still wouldn't do it because I mentally could not farm BG's that many hours for 3 months I support the PvP system and think it is great, and acquiring the hugely powerful items is a big reward and a status symbol. in Classic WoW the game is less about YOU and more about your guild. even if you are not the person to get rank 14, or a Legendary item it still feels awesome when your guild mates get them because it will make your guild stronger. LOVE IT!Agonyy107 Nov 15
I hate to be the one to say this, but let’s face it: we’re not little kids any more. Even for those of us who played Vanilla when they were well into their adult years will have gotten 14 years older, 14 years wiser, and up to 14 years more experienced with video games. What does that mean for Classic WoW? Well for starters, the grand majority of people who are interested in Classic will now have full time jobs. Some might have families and kids they didn’t have before. Basically, WoW Classic won’t be a big of a chunk in people’s lives as it was back then. Considering how much time you will really need to put into Classic WoW to enjoy everything it has to offer, that might be an issue. Stringing together 40-odd people to storm Blackwing Lair might be significantly more difficult now than it was back then. However, due to the issues I talked about in the paragraph above, it might not need to be the long, arduous hours that many people put into Vanilla raiding. With the right preparation and knowledge, raids in Classic will most likely take considerably less time to complete than they did in Vanilla, which will hopefully counteract the fact that the majority of players will have less overall time and fewer long chunks of time to play. 6. Conclusion In essence, the game itself might not be changing from Vanilla to Classic WoW, but the knowledge and mindset of the players of the game will considerably change the way the game feels. Everyone probably figures that there won’t be that same sense of wonder that Vanilla WoW brought so long ago, and that’s true. Nostalgia can only carry Classic WoW so far. Thankfully, I believe that there is some truly solid game design inVanilla WoW, and the fact that Blizzard have doubled down on creating a verbatim experience for Classic WoW is something that people have been adamant about since the day they announced its release. Only time will tell if ClassicWoW truly is the thing people have been wanting, or whether the new CEO ofBlizzard Jay Allen Brack was right – we thought we wanted it, but we didn’t.
Gold in World of Warcraft: Classic can be earned with a bit of luck too. By killing and looting mobs you might find some truly rare items. Some of them might be usable by you but others might not. Don’t just sell that piece of rare equipment to the nearest vendor as it can earn you quite a bit in the auction house. Especially if it’s an item for a level 50+ character.
Nov 15 Classic hit me like a truck I had no interest in it what so ever. After watching the blizzcon demo - I can’t stop thinking about it. The combat it’s so visceral. The world is so much bigger and so much more dangerous. Each fight reminded me of dark souls. I’ve been watching only classic and vanilla vids since blizzcon, it’s actually ruined retail for me. I was actually enjoying raiding in BFA but now I don’t want anything but to play classic and immerse myself in it. What is this sorcery? I heard vanilla wow was addictive, but really? I feel like I’m in withdrawal and I haven’t even played it yet. I think I’m in trouble once it releases. I don’t want to log into retail anymore :(Gripp204 Nov 15
So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years. 

Blizz stated in a watercooler that they're using the 1.12 database as a starting point. I don't think it's a stretch for people to assume that most game features and mechanics will be in their 1.12 state. The kind of stuff I would expect to see reverted would be numerous AV changes, but I seriously doubt class mechanics are going to be reverted. I'd be surprised if the threat changes that ruin pre-naxx encounters are reverted.
