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.
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.
The leveling guides on my site are essentially speed leveling guides.  My leveling guides are the same guides I use myself to speedrun to 60 on new servers to get 60 server first.  I list many occasions where I tell the player to "die on purpose" to go faster.  I tell the player to skip certain quests, because some quests are just not worth the time/XP.  I list tricks and shortcuts to go faster so you can reach level 60 much quicker.  I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow.  For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways.  Although I do list quests that can optionally be done if you have a group.

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.
To fill our pool of beta and stress test participants, we’ll be choosing dedicated players who meet select criteria from both the WoW Classic beta opt-in and the standard Warcraft beta opt-in. Participants will also need to have an active subscription or active game time on their Account. While opting-in to the beta is the primary way to make sure you’re in the running to join the test it doesn’t guarantee an invitation to the closed beta test. We may also consider additional factors such as how long a player has been subscribed to the game so that we have the right mix of players to ensure great feedback toward making WoW Classic the very best experience for the community.
Nov 15 My only complain about Classic... ...Horde doesn't have any nice looking races. In my mind each class has best RPG based race for it. So, I like Gnomes because I feel them Mages. Night Elves - Hunters. Humans - Paladins. On Horde side: Undead - ugly. Trolls - ugly. Orcs... uhh fine as Warriors, but I don't play warriors. Tauren - Warriors or Shaman, again don't play those. Blood Elves! Give me Blood Elves!Vlasta36 Nov 15
