I didn't mention DNC (which could effectively be any role tbh) because of my supposition that the MSK will be the healer class. MSK will use guns and DNC has always used daggers, cloth, or poles. Guns have nothing to do with DNC. DNC could be the incoming tank but I still think 3.0 will bring us to the far east and SAM makes sense (by FF standards, not real-world) to be a tank and the job of choice from that area.
