Haha no I think he is very strong! He can tank very well. Or if it’s damage you are seeking, he can certainly provide that too with the numerous buffs that he can stack up.
I usually prefer an offensive style build with him:
Band of Brothers
I rotate constanly between actives on the Retro and the Claw. Sometimes the Enforcer which has the highest damage potential point blank, though suffers drop-off severely with range (up to a max penalty of -84%). The Retro and Claw are his best rifle options, suffering only up to 10% and 0% (zero) damage drop-off respectively.
