Can we please cut vayne invis to half a second..

At max level, Vaynes Q cooldown is 2 seconds. She currently stays invis for 1 second while under ultimate effect. Within that second, and in teamfights, she is able to reposition herself several times leaving the attacker completely clueless. I really think that the purpose of the invis Q should not be to allow the vayne to completely reposition herself, but to simply briefly disorient the attacker, and not popping up 2 inches from where she used to be. Like that ult allows her to constantly make so much room between her and her opponent(s) where she can usually position herself to condemn you dooming you forever. idk.
