Aatrox's Buff !!!!
is not that great to be honest and for people like me, who never go into a fight without a full bar, it doesn't really do that much..
now, on the other hand.. and i think his W, is a real problem. every 3rd Attack is a bit too much for a champion that can't chain from his own kit (example: Vi's Q and E towards her passive W)
so hear me out how about instead of having Aatrox hits for 200 + (100% Bonus AD) on every 3rd attack, he now instead have 66 + (33% of Bonus AD) on each attack ofcourse i'm Talking about his W at level 5.
Basically, instead of having every 3rd attack doing the damage, every attack will deal damage, so if he attacked you 3 times, you will get damaged for almost the same amount of damage you would've normally get on his current 3rd Attack, and ofcourse the health price, would be, Per attack.
now i haven't thought much about the numbers, but this is my initial idea, and i think this would help Aatrox so much as an AS Champion
you can Think of it, as Udyr's Tiger Persistent Effect, except without the Stance Activation Bonus damage...
