On the damage dealer section. I think the Ult should still scale off of AP and not AD. If you overload a kit with AD ratios on every ability, you run into balance issues.
It's fine as is, but he does need something to make him have more of an identity. Your proposed changes would make him even more facerolly than Riven in terms of ridiculous ratios. I like the Tankier proposals, but his R again is an AOE nuke and having that based on health is also problematic; see
.
I don't know if Riot can give Aatrox what he needs to fit thematically into his lore without some sort of rework. Right now, he is just a generic fighter with a revive. I like the mechanic of the blood well, but I think it shouldn't be the only thing about him that makes him unique. If they were to buff him too much, he will become OP very easily, but keeping him as is doesn't give any real reason to pick him over another fighter.
I've thought half-way on this, but one rework I thought of would involve having him have different effects on abilities based on which stance he is in "Blood Price" vs "Blood Thirst". I'm not sure what specifically those effects would be, but they would compliment either offensive or defensive play (extra damage could be a thing and would probably cost extra health; maybe granting defensive stats when casting Dark Flight in "Blood Thirst" stance).
I think that would be a longer term rework as Aatrox is fairly new in the game (as compared to others) but it would actually probably compliment his "am i a tank or a damage dealer" state he is in right now, but giving him more dynamic play (it would also make his micro a little harder).
The only other thing I see happening for Aatrox would be to buff his Ult to grant a buff to nearby allies (kinda like
) that would give Lifesteal and Spell vamp for a few seconds. This fits with his theme as a champion of slaughter who inspires those on the battlefield. Balancing out the lifesteal and spell vamp duration and amount would be a little challenging to balance in his current state so it would probably accompany some nerfs in other areas of his kit, which might make him a champion who was completely dependent on his ult which might not be such a great idea, but it might be able to accompany a rework in the future where other things may be more balanced out. If it were to accompany the rework I hinted at, it could give different stats based on if you were in Offense or Defense mode (spell vamp and lifesteal for defense mode, AS and MS for offense mode (I would say AD and AP, but I wouldn't want it to be copy/paste of Taric). Maybe he would be overloaded if he was able to give buffs to allies, but I'm at design stage, not balance :P.
His patch history is relatively uneventful for being a 2 year old champion. I don't think he really delivers on what he is supposed to be based on his lore though, and that's kind of disappointing. He does better in small skirmishes than in teamfights (where he would seem to be very strong in based on his lore). I would want to take some of the power out of his early game and lane bullying and put it into his midgame for teamfights and I think allowing him to buff his allies may be a good change, as long as some of his early power is redistributed. (he would still be strong in the early game purely based on his revive allowing him to take fights nobody else would, but his damage is very strong in the early game in a duel)
I know this is probably a ways off from being priority for Riot, but I do think Aatrox needs something to make him more exciting and interesting to play. Ultimately, I really long for some sort of buff to allies to his Ult. (his Ult would probably need a shorter duration) It really makes sense to me thematically, but I understand that balancing him afterwards would be difficult. I just feel like he needs something to make him at least a niche pick for certain team comps. Right now his best bet is being an Orianna ball delivery system, but other champions can do that somewhat better than him and then have other things to fall back on. Right now, he's a duelist, but I would like to see him more of a teamfighter.
Thank you if you read this. Any feedback would be appreciated. Good luck to everyone. Peace.
