Dude, 31's are USELESS for Crota. Have you even done the fight? Jesus Christ. The ignorance of you kids on this forum is absolutely shocking. 31's get one hit by everything. They can't help in any aspect of Crota whatsoever. They are getting CARRIED and I'm so -blam!-ing sick of you naive children coming here to complain when you have NO IDEA how difficult Crota already is. You are an IDIOT if you think otherwise. It ha nothing to do with skill. It's pure mechanics for -blam!-s sake. Get it into your head and stop wasting time bitching on the forums. The fight is hard enough as it is. There is no room to carry some scrub 31 around. Period.
