And that's pretty stupid, the main goal of a mmo is replacing stuff with better stuff. And classes ALWAYS evolve too (so old stuff becomes suboptimal), even if you don't like that, Wow is the mmorpg with the most balanced classes and you cant deny this.
If it's more intersting for you, fine, but that's not what I want at all.
There would be no reason to farm new raid or a new season of mm+ if the stuff was not better than the previous tier.
You don't seem to like MMORPG or even RPG. The goal of any rpg is to get more levels OR/AND better stuff
