To fully understand the interplay, consider terrain. This includes the placement of hills and valleys, trees, buildings, and more. When hooking up the old terrain data files to the new modern game system we realized that the way the system looked at the shape of data was different. This resulted in the updated system and classic data not aligning, resulting in weird issues like Kolkar campfires underwater or burnt-out trees from the Cataclysm era appearing in the original world.
Other decisions were slightly less clear cut. At one point in WoW’s history, there was an 8 debuff limit on any one target. This was later raised to 16, and today there is no debuff limit. Thes change radically changed the balance of classes and strategies players could employ when using these debuffs to overcome content. To preserve that balance—and to avoid the slippery slope of retuning patch 1.12 data to compensate for such modern-era changes—we’re looking at setting a debuff limit of 16 for WoW Classic.
In terms of what the World of Warcraft Classic Best Classes are, Warrior and Priest stand out almost instantly. This is partly due to the fact that Protection Warrior is the only viable Tank Class in WoW Vanilla Patch 1.12. Both the Proc Warrior and Priest are required for Raids and when combined in a PVP setting can be a fierce combo on the battlegrounds.

You can’t go wrong with a mage. In fact, Mage was the most popular class in World of Warcraft: Classic due to their ability to farm with ease. Back in the day, the player majority even leveled mages as alts in order to gather gold quickly. In addition to their monstrous ranged DPS, mages also have tons of useful utility. As a mage, you’ll be able to conjure food and water, place portals to the major cities, and even earn gold from doing so.
This is, in my opinion, the largest change that WoW Classic will have over Vanilla, and it’s something that simply can’t be undone. Back in Vanilla, guilds were very secretive over strategies of how to correctly defeat a boss. Videos of boss kills were virtually non-existent,and strategies on how to itemize and play various classes and specs were hard to come by, especially for newer players. This, in addition to the unforgiving raid requirements and difficult content, lead to a lot of the player base never really getting to see a lot of the endgame content. Those that did rarely ever did so efficiently, and it wasn’t uncommon for the best guild on any given server to take months to complete a raid tier. There is absolutely no way that this happens in Classic. The raids in Vanilla are very much a solved system by now. Every raid, and every boss and trash pack inside, has been thoroughly strategized and talked about to death over the last 14 years. Rest assured even if you and your friends never played Vanilla, someone in your raid party will know exactly what to do on every boss, exactly when the trash packs are going to respawn, and exactly what buffs and gear to get to prepare. That certainly doesn’t mean thatClassic raiding will be a cakewalk, but it will be different than how the majority of people stumbled through the content.

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]

In OSRS, before bonds (their equivalent of tokens) were released, there was a strong gold industry, but most people who bought gold did so by buying bonds on the main game, then finding a dedicated 'swapper' who'd exchange their RS3 gold for an appropriate amount of OSRS gold (taking a cut for themselves, of course). I wonder if a similar system will pop up in classic wow
Note: My goal here was to create a comprehensive list of everything you'd need in order to learn to play any class (from Level 1 to Naxxramas)—meaning I am only including class-specific resources here (so no profession guides, general leveling guides, etc). Teeb's Resource list is much broader in scope, and I highly recommend you take advantage of it (as it contains a plethora of non-class specific resources as well). If you're not aware, Teeb is also responsible for the Race & Class Comparison Tool, Dungeon Tier Sets Gallery, and a huge variety of other insanely useful resources.

Ion Hazzikostas: "... an engineer named Omar Gonzalez, who is on the Classic team, tried the method of taking the modern client, the modern server and teaching it to interpret the old 1.12 classic data. He kind of locked himself away for a few weeks, and came out with something that was a prototype--it was very rough, contained tons of bugs, the world wasn't fully rendered, but it was the original classic world, pre-Cataclysm. It had the original skills and talents, and we knew there's was a ton of work to do, but we felt like we realized for the first time, "we can do this." "
You will see a resurgence of power leveling services, item trade services, and gold farming. Classic will have a fresh economy meaning for your average gold farmer time spent in classic is way more efficient. It will probably be worse than it was back in the day. Just look at the blizzard group finder on retail, littered with advertisements for m+ boosting websites. Disgusting. There will be so many gold farmers blizz probably won't be able to keep up. And this is what I truly fear because if the gold farmers start to win activision will step in and introduce wow token. And classic will die.
I am currently working full time on my Vanilla WoW leveling guides.  Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area.  As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return).  Or you can donate directly with PayPal if you like.  All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.
