Morellonomicon puts Grievous Wounds on Aatrox revive passive.
This is pretty game breaking for an Aatrox. You already revive with low enough hp to be insta-gibbed as soon as you get out of passive. With grievous wounds on his passive its even worse. Its been there for at least 2 months, thats when I started to notice it. The problem is coming from morellonomicon, because whenever I see grievous wounds on my passive I press tab to see if anyone has it and sure enough somebody does.
I wish I could get something from Rito telling me if they've started to fix this glitch or if they have even noticed it.
