And the items particulary that make him op:
Dead mans plate
Throw in a cleaver (not op) for that armor penetration, damage and more hp to finish the build and your set to win the game.
Im not kidding here. You can literaly stack your hp up to 4500+ and have a base damage of 320+ while having the most ridicilous instant 1000+ hp healing factor involved. His ults literaly remove 2/3 of your hp once you have those 4 items.
If you dont believe me at all and youre saying im just a moaning bitch who doesnt know nothing then believe me, go and test it out yourself right now.
These items need a nerf asap.
