I just want to be able to play what I want w/o people saying, "Do you mind NOT playing that it's pretty shitty."
I've solved this issue for myself by only leveling the stuff I want to play. If people are against me being a PLD tank, fuck 'em~

Yeah I know, "good luck with that" is the proper response in this case... but I'm fairly confident that job balance will get evened out eventually.
