After this past year of working on this project and forging our way through the various bugs and challenges, one consistent theme that’s emerged is that the difference between what we have and what we want is clearly visible. When we look at today’s World of Warcraft, we can see the differences between the modern game and the classic one. If we tried to update the reference client, we would have instead been tracking down a lot of “invisible” changes such as exploits waiting to be abused, crashes that don’t show up until you have millions of players online at once, and more. We chose to approach the problem in a way that makes our job clear and obvious instead of difficult and hard to see. 
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.
People often forget that what we call “Vanilla” in World of Warcraft was anything but static. Blizzard overhauled the functionality of every single class during the original base game. God knows it needed it. There were two basic ways for Blizzard to approach a vanilla server. The simple — “simple” — method would have been to simply dump all the “Vanilla” content as it existed the night before the Dark Portal opened again and call it a day. But that’s not what Blizzard is doing. Instead, the company is attempting to recreate the actual server-wide experiences people had with content, including major world events and new introductions.
The original animations have also been restored, but WoW’s animation system is tightly coupled with its gameplay code. We had to make changes to both data and code to get the animations back to the 1.12 look. We ran into a few bugs along the way, such as models that should appear prone instead appearing upright, but we were able to correct these with a few fixes.
Notez que lors de la sortie du jeu, le mardi 27 août 2019, tout le contenu ne sera pas disponible immédiatement. Celui-ci sera déployé en 6 phases. En effet, les développeurs souhaitent attendre et voir comment la communauté s'approprie le jeu. Blizzard partagera le calendrier lorsque que les développeurs auront une idée plus claire de la façon dont les joueurs profitent du contenu. Nous vous proposons un calendrier qui sera mis à jour dès que les informations seront disponibles.
To gain gold in World of Warcraft, you will primarily be grinding professions which are fantastic for receiving rewards. Mining is an example of a great profession at an early-game level. While Herbalism is actually the best gathering profession, the issue is it uses consumables which can make the profession rather costly, with the investment required.
For another example of lighting, we looked at Elwynn Forest. We had a period in Warcraft’s history where we changed all the lighting equations and as a result, our environment artists had to take a pass over all of the zones to improve the lighting and take advantage of the new equations. To recreate the original experience, we had to rewind those changes. The first thing we did was restore the old lighting data. This brought us much closer to the original lighting—and with a few more changes to the distance formula, fog formulas, and some changes to shadows, we were able to bring things even closer to the original lighting.
I don’t doubt that there’s a hardcore group of players that want to experience the original game. I have some of my own nostalgia for this period, though I don’t think I’d roll a Paladin again — having spent 2+ years as one originally, I feel like I paid my dues already. But I wonder how many people will fall back in love with grinding thorium ore or black lotus by riding endless loops across the EPL or Winterpsring, pausing only when forced to fight for a node or when dazed? Do folks want to go back to the era of one-tag-per-mob, no kill sharing, slow leveling, slow movement, and the difficulty of finding 39 other well-geared and at least minimally-capable humans to spend 3-5 hours per night, 3-4 nights per week slugging out in dungeons and instances?

Earning gold in World of Warcraft: Classic is all about optimizing your spendings. Back in the day, your character’s skills were acquired from a trainer, using money. Don’t just buy everything he or she offers! Read the skill descriptions and be mindful about them. Quite a few characters can live through the levelling process without learning some of their utility or damage spells. These won’t go anywhere and you’ll be able to learn them later on.
Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.
There is an Action Bar at bottom of the User interface. Each class starts with some skills. Every few levels, you will unlock new skills specific to your character class, these can be learned from your Class trainer. You will be introduced to one of these NPCs during one of the first few quests you complete in your starting zone, but they can also be found in many towns and each of your Faction's cities.
A demo of the game was available at BlizzCon 2018, and was downloadable on home computers for anyone who purchased a BlizzCon ticket or virtual ticket. The servers became available when Opening Ceremony started at BlizzCon 2018 and was set to end on November 8, but was extended until November 12.[4] Players started at level 15, and the only available zones were Westfall and the Barrens.[5] It was based on patch 1.13.0, essentially patch 1.12.0 ported to a modern infrastructure. The first day of the demo, there was a playtime limit of a cumulative 60 minutes with a cooldown of 90 minutes, applied through the BlizzCon Exhaustion debuff.[6] The debuff was removed on the second day of BlizzCon 2018.[7]
Rogue combo points posed another challenge, because the game’s modern resource system knows how to gain and spend combo points, but not how to lose them when changing targets. There are also the older combat formulas to consider, so we had to bring back the code for the prior combat formulas including critical hits and crushing blows. Their chance to occur is also modified by the difference between the defender’s defense and the attacker’s weapon skill. Yes—weapon skill is back. We had the data for this aspect of the classic game, but we also needed to restore the code that increased your skills when you used them and made your skill level affect your chance to hit or get a glancing blow. 

Kaivax, a WoW forum community manager, revealed that WoW Classic's class design, battleground mechanics and stats on existing items will be set to their 1.12 state, despite the game releasing content that expands beyond that. This removes "progressive itemization," so if the stats on a specific piece of equipment was changed during the original updates, that won't take effect in this version.
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
The item they're dropping is the Fused Wiring used in a variety of engineering recipes such as: Field repair bot, Gnomish cloacking device, Goblin jumper cables, mechanical dragonkin and so on. The drop chance is estimated to be around 6% and due to the fact that there only 3 spawn points and this is the only somehow efficent place to get it... the price of it on the auction house is anywhere between 5 and 10 golds, sometimes even more.. you know.. supply and demand.....
And for talent builds. I prefer to make my own talent builds. But I've been playing RPGs since the 8bit days so half the fun is building my own characters up. I already made and bookmarked 1 deep fire mage build, 2 elemental mage builds, and 2 deep frost mage builds. And I might remake them tomorrow if I read up on any good talent choices I left out my 1st 5 times lol. And I have multiple builds for the other classes I play too.
