improvement on Aatrox's current state
Please Red hear me now! I know you guys are like the treants in LOTR but Aatrox needs immediate attention.
I honestly enjoy his changes about the same as I enjoyed him unchanged. However, we are very close to seeing him in the best spot he's been in since induction.
A few -reasonable- suggestions.
Revert E (Blades of Torment) back to magic damage and give it back the AP ratio. This will enable him to interact with armor stacking. This is important because of the prevalence of auto-attack debuffs from items and abilities which itemize armor. It even makes sense logically, it's a spell which is magical, therefore should do magic damage. Revert the AP ratio to allow flexibility with itemization. I know this suggestion is counter-intuitive to the effectiveness of Black Cleaver on Aatrox now, but please for the sake of imagination. Guinsoo's is still really good on him, and the ratios allow for maximization of item stats.
This might seem slightly unreasonable, but allow E stacks to give bloodwell charges which do not decay. Allowing for more access to this blood rush steroid. It makes sense because now E is the only ability which costs health, so it's return should be more rewarding even if it misses or simple is used to gain a stack. Also, once Aatrox is forced to poke farm with E cause he's getting zoned (always lol) it gives him something to work with and keep his bloodwell passive somewhat healthy in the likely event that he gets dove. Being dove with no stacks and no possibility of your passive revive is pretty depressing.
Now that we've discussed changes to his E now let's discuss the loss of his innate attack speed. This is monumental to his success. Aatrox's autoattack is so clunky now with no attack speed. So many autoattacks get canceled because his animation is -SO SLOW- that you have to stand still and wait until the hit registers before you can move again which kills his chasing potential.
He needs innate attack speed buff somewhere, that was his thing! (a rapidly decaying 4 second steroid doesn't count) In order to stay healthy he needs attack speed. A quicker auto-attack animation similar to Fiora's will also ensure that he connects with his basic attacks.
I will continue to make edits to this post with more suggestions and hopefully we can be heard.
