I realize this isn't news to some people, but for those who don't already know (and i know many don't because i'm constantly telling my raid groups about this), running the lamp section with icebreaker is a HUGE help. You can turn around and no scope/quick scope into the crowd of thrall and it will destroy most if not all of them, not to mention you get the +2 Agility. Give it a try.
Edit:
MIDA sounds like another great weapon to use for this. Unfortunately though, i do not have that gun. So i can't try it out. :(
