Note to anyone that thinks Aatrox should get an area buff on his ult.
You are ignoring important facts for the sake of following a bad idea. there already was an ally based area buff ult, and no one cared about it.
remember his old ult? it gave his allies a damage buff. did any taric use it for the damage buff? maybe, but it was underwhelming, and it had to be, because area buffs do not work in this game for tanky characters. they either become overpowered in the most boring way and/or they get nerfed for having invisible power.
I am not saying aa doesn't need changes, he needs something, if I were to say what it would just be an aoe effect for his auto's on his ult instead of attack speed and aoe burst.
