yeah i know. i see it as a learning experience. i'm playing a bot game to see what lifestealer is like and that makes his ulti pretty worthless (you just have to guess when they'll go near an enemy).
but there are heroes where's it's really obvious what you're doing (drow, lich, wraith king), and playing as them is fun. with a hero like lifestealer it's completely unclear to me what his role is supposed to be. you can't stun anyone, you can't lock anyone down, your right-click damage doesn't seem that good (if you don't have items)...it feels less like being a jack of all trades and more like a jack of none of them.
