You probably have problem hitting bladedancers which are actually jumping (which is hard, of course, but they give you the same troubles as gunslingers and every single hunger that can actually jump), but are you serious about having bad times hitting bladedancers which are blinking? Blink is only useful when you need to run away from someone, it was nerfed so many times already that I can't remember any relevant player who is still using it as main way to play, except DiffizzIe (who mastered it and who is extremely good at it, though he doesn't use it to run on you with a shotgun, what a coincidence).
