So I didn't read every comment but what I gathered is: game too casual. Healers bored and does to much dps with said lack of healing need. Tanks gen way to much hate and thus don't need to focus on it and with above healing they don't need to worry as much about defensive moves and thus spend more time dps. And a counter argument being that the community won't change with design changes to clear content so there's no reason to try and tweak it to find a better balance. I miss anything?
