I mean, this is why most MMOs do not change their jobs every dang expansion/major update. They may add upgraded skills or new ones but those changes hardly change the combat and sometimes even give more options on how to play a job instead of being locked into meta play style. It's long overdo for the devs to reconsider how they want to revamp jobs in the future that doesn't involve them constantly reworking jobs each expansion. People will naturally get attached to whatever they started the game with and as soon as they take what they love away, just creates more angry WoLs.
