Are Arenas balanced here?

Wondering if I should start playing arenas, how is the balance?
I heard warriors streamroll any other class by far, and rets.

Its same as everywhere else. Holy/Arms dominate for most parts since its very strong and very easy comp. Ret/MM, Disc/Almost any dps do pretty well as well.

Top 5 teams at the moment I'm writing this comment are hpala/warr. Just a friendly heads-up.
