Possible Aatrox W Bug?
I was trying out the new Sated Devourer on Aatrox and I went to solo Baron after Sated + BoRK + Hydra were completed. I expected my W Blood Thirst to proc every other attack for massive heals on hit, but it didn't EVER proc while I was attacking him. Is this working as intended? Can Aatrox proc his W off of Baron, or is this a bug?
