Since the poksau release with an absolutely insane passive of -50% armor, warriors have been struggling to survive against it… So I suggest the next self buff passive to be some kind of turtle casting you a shield that adds to your total hp%(25-35%), as well as armor(same scaling). Maybe it could also have the weaker ebon aegis mechanic(damage refraction) and it this case the shell it gives you could be spiky as well!
