The Crimson Reaper Passive

So recently I was looking for a new mid and top laning champ and stumbled across Vlad, I like him, good poke and very good team fight. But until I bought him, I wasn't aware of what his passive was and now I know, I like it but could it use some updating so it doesn't copy Ryze? I think it could. So how about this: When Vladimir kills or gets an assist, the champion bleeds when they die (similar to the way that Vlad does when he dies). The animation for their death leaves behind a pool of blood which Vlad has to pick up (or absorb) in X amount of seconds, this will grant him X amount of permanent AP and health - like his current passive does when he builds AP or health. Obviously however Vlad's ulti can become very strong so the passive should have a cool down that allows the ability to be strong but not OP - maybe somewhere between 1.5-2 mins?? Please leave a comment with your thoughts and I hope the idea is considered Makhlas
