Is It Really Necessary For Zed To Blink Behind You + an Untargettable

And someone is still complaining about Zed lol

Not a blink, blinks are instant.

is it really necessary for fiz to have a high dmg invincible ability on a 6 second cd?

It is necessary. Stun him, work wonders. Take exhaust, build zhonyas, qss, get some peel, flash ffs. He's riddled with so much counterplay but everyone that still complains is "muh mana-regen rush spell spam"

It's extremely telegraphed. With proper timing you get a free skillshot hit after he ults

Yes.
