Why is W "out of place on a carry" ? It gives him a disable, a (little) nuke, a gapcloser and an escape ! It's perfect for a carry !

And his ult's range is kinda what makes this ult, plus it cost a hell loads of mana, especially if the target exit your sight (just enter bush) and you have to cast it again.
