Aatrox's resource bar idea
Just change Aatrox's abilities to where they cost a flat amount of health and make it to where whenever Aatrox uses an ability it fills a percentage of his bloodwell. This would make building hp on Aatrox actually better than it is right now and players would actually have a reason to build some cooldown reduction on this dude. It could be just the little boost he needs to not be OP but not trash tier either. Whenever I would play Aatrox I would always buy a botrk, thornmail, spirit visage, and merc treads/ninja tabi. Make his ult not fill his bloodwell anymore, instead make it to where this bonus attack speed goes over the cap and can't be reduced for the duration. If it seems too strong make it to where he doesnt get bonus range off of his ult anymore. With just these few touches people would actually have incentive to buy some hp items and some cdr items. Black Cleaver would be perfect for the guy. The blood god wants blood not his ass being handed to him every time he lanes.
