Am I the only one who thinks a good portion of the flash combos are simply unfair?

By flash combos, I mean combos like flashing during Gragas E animation in order to land the stun on somebody that likely isn't in the path of your dash, or flashing during the Illaoi ult animation to change the location of the AOE.

I think in most instances, they can be ok like Lee's flash ult because it's already guaranteed to land, or Alistar flash q because it's basically instant already.

I really don't support cases where you can change the AOE of the ability by flashing. In my opinion, if you whiffed an ability, that's on you and you should pay with the cd of the ability.

If Blitzcrank could change the direction of his hook mid animation, that would be broken. So why can somebody like Jarvan flash at the end of his knockup and hit somebody who wasn't going to be hit by it.

EDIT: I think it's unfair because how is the enemy supposed to react to an ability that would not have hit, had the enemy not used the flash trick.
