There would be no reason to have the Cataclysm expansion for WoW Classic as it it changes everything and I really don’t want to have any stupid pandas so Mists of Pandaria is out as well.
And everyone and their dog tells me that Warlords of Draenor was terrible so that is out as well.
Legion and Battle for Azeroth might be good expansions for WoW Classic though but would be at lower levels compared to Retail due to Cata, MoP and WoD getting ripped out.
I’m all for the classic talent system, no LFR and no flying mounts but I’m also for TBC and WotLK… and you can have it both ways if Blizzard makes it so in WoW Classic.
Tbc and wotlk have the classic style of talents with some balance changes but cata and forward doesn’t. Also tbc and wotlk have no lfr and flying is ristricted.
