I'm saying powers are not balanced not that they should be required or not. You'll end up using certain things and not other things because there is no advantage in having those, it's not about playing the way you want. I have an easy time to choose what I want over the others here. wind blast? what's point? for example. it's true pretty much for all the power in the lower part.
edit: the other thing I feel it's poorly done, anyone who has played some stealth games would notice here how simplistic are the AI patrol routes, they cover really really tiny spots and don't turn around much, usually conveniently looking at walls,, ghosting this game is super easy, specially indoors where AI pretty much remains in their own spots. This game feels far more basic in this regard than from the likes of classic Splinter Cell, Hitman, Thief or Metal Gear. The AI overall is very disappointing.
