Don’t overly balance classes and builds though. I don’t want to see a WOW like scape where every class is essentially the same thing. Some classes are just going to be niche due to its mechanics and that’s okay. Guild Wars 2 does this very well and that’s why I still love that game despite the graphics being really old.
Homogenization of WoW classes in later expansions hurt the game significantly IMO. BC and Wrath were fantastic. I’m also one of those that are of the opinion that flying mounts were a huge mistake in the game.
