I think that the token is a nice solution for the problem. Back in the days, blizzard tryed to ban gold sellers, but it was a lost cause. Instead, the token seems to have resolved the problem, letting workers that want to raid with consumables and stuffs to have the golds to do it. Personally, I don't find the gold buying really fair, but I understand that for many people is a necessity and I prefer to leave the economy and the farming spots to the player instead to the gold sellers.
There’s the reason why some players used to call the game World of Roguecraft. Rogue was one of the most popular classes in classic WoW and there’s a good reason for it. During vanilla, Rogues topped DPS meters in raids and dungeons, but their main strength was world PvP. Rogues could stealth through enemies avoiding unwanted engagements with the opposing faction. Additionally, a huge variety of crowd control abilities and high burst damage made them the worst nightmare for the cloth-wearing classes. However, Rogues were in a bit of disadvantage regarding end-game gearing since most of their gear pieces were useful to other in-game classes as well.
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.
Instead of sharding the zones, their plan is to shard the entire continent at launch. In Classic WoW, there are no dynamic spawns and questing in starting zones would quickly become annoying, so it's understandable that the game is all but fun when there are no mobs to kill, but layering will also cause you to see new players, every time you sign in to the game, which is a clear downside of the tech.
After choosing a race, class and customizing the look of your character, you will spawn in your race's starting zone, usually within a small settlement. Typically, these beginning areas are designed to get you to around level 10 before you leave and move on to the next zone. Right away, you will notice that some NPCs have a yellow exclamation mark () over their head. These symbols will also display on the mini map in the top-right corner of the screen if you are close to them. Talking with these NPCs will allow you to read and accept a quest they have for you. The objectives and status of this quest can be checked at any time by opening the quest log (L). Once you have completed the objectives for said quest, you can return to the NPC (or possibly a different one) to turn in the quest. The NPC whom you need to turn a quest into will have a yellow question mark () over their head. As you complete quests and your character gains levels, always be on the lookout for new quests being offered by NPCs.
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.
