Of course that's going to be a strong mentality because this game made damage to be king.
It doesn't help when a large portion of this community wants their time to not be wasted, thus they push for faster clears and faster clears for healers translates into doing more DPS. Healer mains have asked for things to be more heal intense before but that would most likely mean content to take longer, newbie/bad healers to be stressed out and cause even more wipes, along with people instant quitting anything that's too difficult. It's why the only thing we can really ask for is more DPS (variety of buffs for AST) to avoid all that. This game didn't attract the usual MMO crowd that would like all of the increasing dangers the higher level we got but a really casual/first time playing an MMO crowd instead. And some give vibes of this being their first game ever or something.
