From all the video footage I was expecting it to work more fluidly considering how cleanly the demonstrators were using it but in game it just seems clumsy.
One thing I would like to see in a patch is to widen the acceptable area for the climb icon to appear so that it is easier to blink up to something on the fly.
Also I think it would be cool if while you were blinking time slowed a little so you could chain blinks together such as blink up into the air and then blink forward onto an object. As it is you move so quickly that there it is impossible to try to aim another blink.
