Never done arena before, but I have scoured these forums for info. I have a few questions that I can't seem to find any answers for here. (unless they are in the protected Arena forum that I don't have access to)

1) Do you get any points for losing? I'm afraid that I'll suck so bad that I won't win anything for a while

2) It seems like a no-brainer to do 5v5, but some recent posts seem to suggest doing 2v2 or 3v3 because less people are doing 5v5 now, so there are less teams, making wins harder to come by. But wouldn't it both take longer to get points for my 5 toons and make wins harder to come by because I won't have as much DPS on a single target?

3) For elemental shamans, is haste or crit or mastery the best stat for PVP? I recall haste being the best stat in the past, but I'm not sure at this point.

Thanks.
