facepalm
If you have 500 HP you think that Zhonya is gonna save you against a damage dealing champion who hasn't blown his CD?
Ezreal was also just a bit more than half HP, Morgana was surely support and despite the huge base damages she can't do much.
If Riven had half randuins it means that she missed on a damage item, in fact she has only armor pen items and not big AD item to actually deal some damage and have some shield from E that has 100% Bonus AD scaling....
Any assassin would have done the same thing, especially Katarina whose mobility is unparreled if she gets a reset, which she could totally get with Kassadin being that low.
Whoever "Zed main" said that Zed is useless without ult doesn't know his champion well, seeing how his ultimate damage depends on 50% of the damage he has dealt with his non ultimate abilities?
Any assassin can kill squishies with their basic abilities once they get their core items.
I don't remember Fizz needing ult to kill someone that is a squishy and half dead, nor Katarina.
"Morgana and Ezreal should have bought QSS. It's their own bad to die against Zed because they didn't build MR."
WTF DID I JUST READ.
That was a mid game scenario where Zed was at his peak seeing that he has it's meta standard holy trinity of damage.
QSS and Zhonyas won't save you in a 1vs1 scenario or into mid game fights, it's just used to bait and deny Zed a kill into a lategame fight so he fails to execute a key member of the enemy team and be a semi-useless component if he wasn't even able to zone a dangerous carry.
Why you think most of Zeds lategame go splitpush?
This video proves just how burst+mobility champions i.e. assassins are very strong right now because of the pre-season changes, Zed was also kinda lucky with dem crits.
Zed is not a weak champion, but neither overbearingly overpowered as people make him out to be, i fear more a Fed Riven to be honest....
