Ults aren't up constantly, and you really, really need CC to use them, otherwise they're easily avoided. W does okay damage, but you pretty much have to save it for escapes or kill securing, cause you are not gonna get kills with it even on half health heroes...and the shurikens are...just not that scary at all, sorry. I've used it, and been hit by it, and in either case the damage tickles, nothing more.
