I'm not one to start raid teams anyway, so I never restrict who I play with, but there ARE benefits to being a higher level. Defense. Armor with 36 light always has more defense (not to mention Discipline, Intellect, and strength). I agree with lack of extra damage done (assuming maxed weapons, which most players that are newer level 29's or 30's don't have yet) but higher level will reduce damage taken, helping you stay alive. It's tough going in a raid with lower leveled players rocking blue heavys and specials. I love the challenge for me, but I can see where some people just want to get it done.
