I can kill 1 purple boss alone (even 2 if I'm lucky).
I have killed archvillains (post I6) with the help of only one person.
I can kill 8 yellows minions attacking in the same time.
Do I deserve a nerf for that ?
Btw, I'm not a mastermind, I'm only a Broadsword/Invulnerable Scrapper and I can solo a mission ways faster than a mastermind .
