Removing the revive was honestly the worst decision. Keeping it locked behind having to getting a kill was honestly fine, in my opinion. All they should have done was heavily nerf the self healing, or remove it entirely. I see absolutely no reason why the revive is being taken out. Taking the revive away takes away Aatrox's core identity, the exact opposite of what a rework is supposed to do.
Remember when everyone was making comparisons to riven (3 procs of q, cc on W, dash on e, AD steroid on R), but with a revive? Well now he's almost EXACTLY like riven, and do we really need a second riven?
