I propose to add arena 1x1.
I and a lot of other people like solo game. I dont have time to find some partner and also I dont like setups like heal+dd, for example Hpala+Awar or dk+Hpal, or Ret+prist, its really boring.
I think arena 1x1 its really fun, and as I know there is already added 1x1 on last wow path, and people really like it.
