Ironman Infinity War.... More like Rubber boy from LaLa land.  POOR DPS?
I have an awakened maxed out 4* Iron man infinity war,  I usually just use him as an AW defender. Ive seen alot of good threads about him and Seatin says great things about him 
IS THERE SOMTHING IM MISSING. 
I understand the plasma mechanic and have no problem inflicting the plasma debuff. Ive tried a bunch of different strategies and fight styles and he just kinda seems to hit like a pool noodle.  
what can i do to up his DPS?? 
Thanks in advance
