Been playing SMITE TM on and off since beta. I play Arena..just Arena. I would say I'm an Arena specialist but that would make it sounds like I'm some kind of professional at it. I just like Arena.
I play most roles, mostly out of necessity given.. well I play Arena. That does mean I don't play Mage and Assassin a lot, if you've ever solo queued arena you'll know why.
Really I just play on a god by god basis, but without a doubt my main is definitely Wukong.
Other gods that I frequent include:
Jing Wei
Amaterasu
Ah Muzen Cab
Kukuklan (aka. Old Ao Kuang, never forget)
Ra (Support)
Ratatoskr (The only Assassin I really play)
Geb and Ymir (The tank brothers, sometimes you just have to play tank)
That's it.
