I'm using a Zowie AM and I'll probably end up putting melee attack on the forward thumb key and block on the backward key. I've got a Razer Naga and I've never been too fond of it for shooters. If I ever have to bind keys onto the mouse for a shooter, it's at most 1-2 keys and the Naga has so many buttons clustered together that I inevitably fat-finger them. Just my opinion though.
Tactical assault devastator terminator librarian chaplain. The whole squad has to pitch in to make 1 person a chaplain or Libby. There is also a special effect that everyone can see, even enemy, so they know that they were deployed and where. Phone about to die. More later.
