Reasonable change to make Aatrox not awful
Rework his terrible blood well mechanic so he doesn't have to deal damage to himself in order to fill the blood well. Nerf the amount of attack speed if necessary, just as long as he doesn't have to kill himself to get it. There is no reason to punish players for trying to utilize their passive, especially in top lane where the trades usually don't last long enough to fill the blood well.
,
(generates Fury passively with ult) ,
and
all gain Fury after every attack.
passively generates it after level 6 and
generates Rage automatically while in combat as well.
is the only character that has to generate this resource via health costs on his abilities and it's one of the reasons why Riot can't give him stronger base stats because he already has bonus attack speed buried in his passive. This isn't a fun or rewarding mechanic and it doesn't exist as counterplay. I have no issue with health costs on abilities, until those health costs become the only way ramp up in combat power.
