I feel like the new item that allows you to blink a distance will make the game more frustrating

Jumping in on a champion that is weak to being jumped on and then having them safely blink away from you seems very frustrating and being able to do that pretty often considering the cooldown paired with having flash seems like it would be very annoying to deal with especially if a lot of people buy them. In addition, champions with already high mobility will be even harder to escape from or chase down which will make dealing with them very annoying to do. I'd rather not have 5 people blinking around in teamfights and what not for every fight. It just seems like it wouldn't be fun to play against at all similar to Kass's old 850 range ult. Idk that's just my thought on it.
