The notion of ongoing updates as they originally appeared, though, raises the question of expansions. Blizzard has released seven expansions in all. And while later ones like Legion or Battle for Azeroth would feel out-of-place within the Classic framework, it stands to reason that some players may want to experience earlier expansions--such as The Burning Crusade or Wrath of the Lich King--in the context of World of Warcraft Classic. Blizzard isn't committing to this, but also hasn't ruled it out.
The Horde levels 50-60 guide has been rewritten and revamped. My 1-60 Horde leveling guide is now completely updated for the 1.12 Drums of War patch. As you can see it is about 15% larger than the 40-50 guide (single largest guide page yet). There is also a lot of route changes. I moved the entire Silithus section from level 55 to level 58, which allowed me to include a lot more quests for that zone. There is also a lot of other improvement to the route, including adding a lot more quests into the guide, mostly from Moonglade, Silithus and Eastern Plaguelands. This will make the final level 59 grind much shorter.
A different brand of challenge is presented by the PVP, which has undergone multiple phases and metas throughout the game's long lifespan. As in any competitive live game, some classes will be a fan favorite criticized as overpowered in one era only to be left behind in the next. The team says this is one of the main reasons it chose this specific iteration of WoW.
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.
The primary goal of Conflict and Strife is to provide an interesting choice in PvP by allowing access to an extra PvP Talent. It’s not necessarily going to be a strong option for PvE. The acquisition of this Essence is via PvP, and is totally optional for PvE-focused players. While there may be interesting PvE uses for some of the choices, it is not expected to be a strong competitor on usual PvE criteria (like total throughput) on every spec.
