Pass on Arenas. NO thank you.
Objective based WZ maps and maybe 1-2 TDM maps > Arenas.
Arenas are breeding grounds for skilled players...but they are also breeding grounds for a terrible community with a dash of class OP outcry.
ironically 99% of players that post OP outcries in wow forums are casuals who mostly play BG's and never step a foot into arena. (example: blood DKs are so overpowered please nerf!)
top rank1 players usually never post that kind of garbage
