You ever get hooked by a Blitz hook after Poppy launches him away? You still get pulled all the way to the location he was in when the hook hit. You don't like it, buy a QSS. You're going to be held there anyway without it.
On an off note, Blitzcrank's hook and Darius' hook used to pull you to wherever they were when the hook ended. So, for example, as Darius you could hook the entire enemy team as you finished backing, it wouldn't interrupt the back, and you would pull the entire enemy team with you to base. Not to mention that you could also hook Dragon or Baron. Those were all bugs, but this right here isn't: Blitzcrank's hook used to be targeted and longer range than it currently is. Yes, that's right, blitz used to be able to target you into the hook, flash into tower during the animation, and pull you all the way to the tower. That's the origin of the flash hook play.
