I took my Kingpin to 6R3, initially I viewed him as a defender but after some testing I realized that is best use is for attack.
He is already good by himself but paired with Hood he is just truly insane.
With Hood he has 120% chance to purify any debuff (cool down: 0,5 seconds), that makes him super viable for Hazard Shift nodes on Alliance War.
This is a showcase of him defeating Vision Aarkus and Mojo on Hazard Shift...he can kill almost any enemy on this type of nodes!
