Aatrox Ultimate
When late-game comes, in team fights especially, Aatrox presence is pretty underwhelming... His 3rd rank R, does instantly 400 AOE dmg @ 525 range. My problem is, that, late game, even champions that don't have any MR, still have ~40% damage reduction from basic magic resist, so, this means that to the squishiest champs out there we will deal ~240 dmg, when lowest health pool is around 2k hp.
Basically right now, the damage part of his ult is so small, that i think some of League players have no idea it even exists (most of them think it's just an AS steroid).
My idea would be to give him some true damage instead of magic damage on his ult, but, instead of 200/300/400, should be something like 175/275/400, due to the fact of having a potential to be oppressive early game.
