Imagine if zhonya had magic penetration

You know, that's not even a fair and reasonable idea.

Considering Edge of Night has a quarter the cooldown of Zhonya's Hourglass and you're pretty much guaranteed to die after Zhonya's Hourglass wears off unless your team already has the advantage in a fight. If anything, give Zhonya's Hourglass that magic penetration, lower the cooldown on the active and allow movement for the duration for the duration and we've brought balance to the force. Well, after increasing Zhonya's Hourglass AP to actually be equivalent to an AD counterpart.

Well damn, when I put it like that, Zhonya's Hourglass is hot garbage by comparison. I didn't even realize it was that bad until I directly compared the two. Rito, are you high?

I understand they wanted Assassins to be fun to play, but Edge of Night is FAR too powerful. I would argue that it should be built on EVERY champion, regardless of composition.
