Whatever you do, just don't feed the trolls.

Go in geared, groups of 3, do your job well, don't reply to haters in chat. That will get you through most without a vote-kick.

I tried 5, it was too obvious and I was vote-kicked too often. Not because I was bad, the votes were never started based on my contribution just on seeing I was boxing. I never even bothered trying more than that even though I was boxing 10.
