To answer your first sentence, no, it won't use spell vamp even if applied by abilities. It becomes a sort of on-ability effect and works similar to on-hit effects (E.G. you wont get spell vamp / lifesteal from Wit's End damage).

To answer the rest, yeah. When I bought him I thought R pretty much HAD to be evolved to play effectilvely, but actually:

-Q damage scaling off of missing HP is too damn good for finishing off enemies

-W causing AOE slow at range is too damn good for giving the chasing power he needs as an assasin

-E refreshing on K/A and double range is too damn good for the mobility he needs as an assasin

Upgraded R is just... meh. It is only good against certain champs with high-powered ultimates that give you enough of a warning (EG Karthus, Caitlyn)
