I had a fun little idea for an Aatrox rework

Let's talk about for a minute. Personally I like to think of him as the primordial juggernaut. He's tough to kill and does a lot of damage, but he's vulnerable to kiting. He's weak when he first enters combat but the longer he's in combat the stronger he gets via bloodwell. What bugs me and why I think he should be reworked is simply that he's kinda boring in his current state. Here's my idea. Change his ult entirely to something else and fold his current ult into his passive revive. His passive revive right now is boring. Unlike who goes all egg and then revives (hopefully) in ready to fight form or who just starts beating everything that moves on revive Aatrox just sort of hobbles away like a spanked old man. This isn't really fun. Now picture this. Aatrox dives into a team fight, gets bursted down and goes into his revive passive. Except this time he stands up and goes all Sion with a "Witness truth" and instead of hobbling away like a beaten dog he gets back into the fight like he's thematically supposed to. Thoughts?
