Simple Aatrox changes
Lots of long complicated ideas out there. I kinda of like him as he is. The fact that he has to remain in combat or else gain no attack speed is pretty annoying. Many champions have passive attack speed bonuses. That being said...
1)His passive should grant a minimum of X attack speed up to X amount depending on how full his blood well is
2)His blood well should drain a little bit slower and not so soon out of combat.
3)His Q dive needs a little something something. EVERYTHING interrupts it. If Wukong is spinning in his ult and you try to dive (after already being hit by it) you get hit going up and knocked back down. Hes in the air, but Azir's wall hits him. Anyone doing anything will stop his dive and his dive really doesn't interrupt anything. So it needs something. However I am most okay with no changes to this than in other areas.
4)He should be able to permanently increase his blood well so that its possible for him to have some kind of late game benefit--Last hitting minions grants him 1 max HP in blood well, and 5 hp on champion kills and assist. So if hes farmed 150 minions, he has 150 more HP he can store, and 10 kills, 50. This inst a crazy buff. It really just means that he will be able to get a little more attack speed from his passive, and revive with just a little more health later on in the game.
5)His Ult. Its basically just more attack speed as it stands. Yes, some AoE damage and range. I would rather it work like Karma's ult. It just empowers his other moves, with a shorter cool down. His Q would get a longer range and impact area and bonus damage, his W would be wider, longer and bonus damage, and any auto attacks during the 10-12 seconds activate his W, whichever you have toggled on, instead of every third hit.
