I did a Nightfall with this guy once. He did nothing but talk about his immense hatred for Hunters and how we offer nothing to the team. I then proceeded to double his kills and not die compared to his several Titan run-n-gun deaths. He was probably just terrible at the game, but that doesn't give him any room to call an entire class useless. Until you have played each and every class, do not talk about class balance. It makes you sound stupid.
