wow do i not understand how half the heroes in this game work
lifestealer just seems useless to me and yet i'm informed that he's a great carry
It is one of those things about Dota that isn't always clearly explained.
Basically as a carry like him, you have to be pretty cautious with fights early on, and can go more ham as you get stronger.
90% of the time it is about positioning. Just blindly running at your opponent usually isn't going to do it. Early game with him, chances are you won't get a solo kill, you will need help. As the game progresses, you probably can get solo kills, especially against those beefy heroes.
I really want to make a video series on these kinds of things that aren't explained as often to new players, things like why certain items are bought on certain heroes, what exactly makes a carry, the way neutral camp spawning works (I STILL run into people that think it is based on vision), what Faceless Void's Backtrack is, and how MKB won't help you against it, stuff like that.
