So, I just started an arena team with a rogue, and I must say it is pretty cool. None of us have ever played in the arenas before and our gear is mediocre at best, and yet we end up with 11 wins and 15 losses for our first session of arena-ness. Most of the losses involved warlocks with full or partial arena gear... Was really fun though, and we're definately gonna keep on doing this stuff.
