I find that stun terrifying. D:
It can go down at anytime I'm lane without warning, allowing him to get free poke on me and later on, absolutely destroy me.
Zhonya's only works if I'm not stunned, QSS has a 90 second cooldown and doesn't stack if you're a mage or tank. Cleanse is super risky if you aren't playing ranked, and banshee's veil can fail in hundreds of ways, including you accidentally walking inside. Difficulty isn't counterplay because that means whether I win or lose depends completely on the other player. Most non-tank/bruiser builds don't give a drop of tenacity.
You just have to use the smart positioning thing you were talking about and pray to the League gods that he doesn't place it right on top of you or where you going. Now while I agree with a small "wind up" I'm fine with it hitting infinite people and its range. I just want a meaningful chance to dodge.
Zed...well the items work a lot more reliably. Not that that will solve his energy costs, lane safety, harass, and the cooldown of said items.
