@riot aatrox W should be tweaked.

on Pbe its 150 max rank with 75% bonus ad scaling. currently it has 100% bonus ad scaling and around 200

what i am proposing is changing the scaling from 75% bonus to 60% total since generally on aatrox especially the one on the PBE you won't be building has much attack damage has before probably not even life steal since his moves no longer cost health

an example build would be
with undying grasp has his keystone. or maybe even the new bond of stone of strength of colossus

so from titanic and cleaver you get a bonus 75 ad take 75% of that and add it to bloodprice = 56 ad 30% cdr and more then 1000 bonus health clearly lol

which means at full build it would only be slighty over the base scaling has live aatrox , whom already scales poorly into the game against other top laners. much less tahm kench and yes this is bad because the on his blood rush only gives him base ad so it won't effect blood price.

another effective build would be to completely ignore his blood thirst and go: and completely rely on blood rush base ad% gain and use in sync with boosted sheen procts and crits of massive damage while ga helps you survive.

last effective build path would be on hit aatrox which is my least favorite wth the current botrk
