As a feral:
-Don't make Blood Talons the best/mandatory talent... again...
-Stop lying about and designing feral around "classes do different things better" narrative meanwhile other classes can do EVERYTHING better... at once
-Stop giving the already top classes mandatory raid buffs and give ferals something that makes them not the least useless and unwanted melee class in the whole game
-Design raids with melee classes in the mind, so 3 melee and 11 ranged isn't the standard meanwhile they keep adding only melee classes in expansions
-Stop redesigning boomkins every expansion and give some love for feral which is literally the same since Burning Crusade... 13 years
