We can run with three.... ;-)
What kind of bluid do you want to play....
Since its a skills based game you can put almost anything together but to give you an idea of things you generall see:
Close combat specialists (often with infiltration)
Ranged weapon specialists (so pistols, SMG's, Assault rifles)
Face characters (the good negotiators, interrogators etc)
Drone specialists (sit in a van and work through drones)
Hackers
There is magic but lets stay clear for now
Or i can simply post up a few and you can choose.
