Yeah I love amumu's kit all except for his passive and w

1. I think it might be overpowered. But I doubt the sustain from it is crazy since all of his abilities use health and in your example he would heal for 30 hp against a champion, unless he deals damage to multiple champions or minions. And i think it might remove one thing that I hated about playing him: getting counterjungled. Because in the jungle the sustain will be crazy when you try to fight him as someone like Eve with no sustain near the wraith camp.

Also I lowered his bases and scalings so he won't deal ridiculous damage because Amumu deals a  lot of damage for a tank already.

2. Yeah, I was always really annoyed by the CD since you level his Q up last. But it might make his early ganks too strong

3. I think it would be the same range as the active, maybe a little more so 350 would be fine. I'd like Amumu to be a very strong disruptor, but you're right a 1.5 s blind on 5s CD is really strong, especially since it's aoe. I'll change it so that they're next basic attack will miss I think that would be alright.
