Despite using Patch 1.12, Blizzard is incorporating other vanilla World of Warcraft experiences, which will be released in waves. This is the current roadmap:Phase 1 (Classic Launch): Molten Core, Onyxia, Maraudon

Phase 2: Dire Maul, Azuregos, Kazzak

Phase 3: Blackwing Lair, Darkmoon Faire, Darkmoon deck drops begin

Phase 4: Zul'Gurub, Green Dragons

Phase 5: Ahn’Qiraj War Effort begins, Ahn’Qiraj raids open when the war effort dictates, Dungeon loot reconfiguration (Tier 0.5 Dungeon gear, Relics, drop rates and location changes)

Phase 6: Naxxramas, Scourge Invasion

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.

Additionally, any items that were added to a boss' loot table in Ahn'Qiraj will only appear once Ahn’Qiraj launches in phase 5.

Kaivax recently published a blog post revealing that the team is bringing the clock onto the minimap by default, so it's possible that Blizzard may bring other features of the modern UI to WoW Classic as well.

What's the PvP content going to look like?

Blizzard will also be rolling out the PvP content within the previously mentioned phases. This is the current roadmap:Phase 1 (Classic Launch): You can PvP one another in the world, but there is no tracking, and no formal rewards for doing so.

Phase 2: Honor System (including Dishonorable Kills), PvP Rank Rewards

Phase 3: Alterac Valley (version 1.12), Warsong Gulch

Phase 4: Arathi Basin

Phase 6: World PvP objectives in Silithus and Eastern Plaguelands
