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.
I wonder if they’ll execute this similar to Jagex does OSRS. Let the players vote and once all phases cleared and of articles have been introduced, vote new WoW Classic articles to be inserted.

Give everyone a couple of buy classic wow gold months of nostalgia that is pure , then resolve a number of these things.
