As a tank, the better my gear the more indestructible I feel. I can take on more enemies without fear of death and take less damage from raid bosses large attacks in some cases even being able to ignore mechanics that used to one shot me.
As a damage dealer, the better my gear the more destruction I bring. I can kill faster, AoE down packs of mobs I used to have to crowd control and burn through whole phases of boss encounters that used to take forever.
As a healer, the better my gear the less heals I have to cast, the less I have to pay attention to the game, ...and the more TV I can watch as I play.
In short: my tanks and damage dealers get more and more fun to play as I gear them, and my healers get more and more boring.
Does anyone have any ideas how to address this? Do you think it is even possible to fix? Or do you completely disagree and think there is nothing to address?
You could say "just start throwing out some DPS!" once you out gear things....but tanks and damage dealers don't have to completely switch roles once they gear up just to keep the game interesting.
