Just read on surrenderat20 that 
or 
no longer removes all disables. It only removes cc. Now correct me if I'm wrong but does that not mean that Zed will be able to get his ult off even if you have QSS? If so that means supports who fight against Zed will have to prioritize 
FACE THE WlND2 votesMikaels doesn't remove Zed ult, never has.
Hethalean1 votesAs another point, it won't remove Malphite or WW ult
ModWulf Helhammer1 votesYes it will. Those are CC, not debuffs
Hethalean1 votesFrom the wiki
UNIQUE: Removes all stuns, roots, taunts, fears, silences and slows on an allied champion and heals for 150 + (10% of the target's maximum health). (180 second cooldown. 750 range.)
It does not list suppress, knockups, or blinds.
ModWulf Helhammer1 votesThought you were just talking about QSS, not Mikeal's
Live2LetDie1 votesQss was the only one to "remove" zeds ult. Now hourglass is the only way to avoid it's damage
Chaos6891 votesNow, it means that zed is even MORE disgusting
