You play with the wrong 32's. I bring level 28's through Crota's End all the time, duo, solo, or having 4 28's and a 31 with me. Shit doesn't matter, just as long as you know what you're doing and listen. I remember being a 29 and was invited to a raid from LFG. I joined the group and immediatly they said "Hey, undead is a 29, kick him (they were all 29's, pre dlc of course). I clearly stated I was a 29, 20 raid completions and had weapons needed to get through (Specifically: VoC, Found Verdict/Praedyth's Revenge, Gjallarhorn) and they invited me just to kick me. I don't like that kind of shit and try helping as many people as possible when I can.
