His passive is very usefull for jungling and even later in the game. You know those times you lived with less than 40 HP left? And how many times it procs in the jungle?

If you would give him CC-reduction, he would be OP, because you couldn't stop his ult from work anymore. Instead, with my rework, he has it a bit easier while his problem is still there. If you 100% solve the kiting problem of a meele ad, he is OP.
