@Riot: Can we redefine suppression as a form of mechanic?
I think that we need to redefine suppression as a game mechanic as there are a lot of misconception about it and not to mention suppressions aren't really strong enough when compared to knockups and other forms of CC. Because I don't see why suppression should be countered by an Item at all when most of them have inbuilt counterplay already.
Let me explain.
Suppression is supposed to be just more than a stun. It is supposed to be a SUPER CC that lasts long and are only available on select few champs 

, thats why things like tenacity,
and
don't work against it, but why on earth do we have
?
The problem with this is that from all the options to remove CC you choose only this item to break suppression. So whats so super if an item can break it? Not to mention this build path only contains AD and that building this item often feels like a waste or sets you back alot, but thats fair because now 
they cant CC you right? Well, its kinda not fair the person having the suppression because, the common trend with suppression except for
and
is that you are standing in 1 spot and channeling the effect fully exposed and can be interrupted by the simplest nudge. I mean thats the counter play Suppression should have.
is a low mobility mage which realistically means that if he ever wants to complete a full ult he has to ulti a lower priority target(meaning whoever dives the hardest into the team), or commit a flash and be exposed to a supports CC if he ults an ADC.
However dives inn, but he has the same issues he will rarely do a full cycle(1.8 seconds) and I mean why not just use
who cant be interrupted and holds down the enemy for 1.25 which cant be cleansed, who also has follow up CC if I might add.
Suffers from the same problems as Malzahar however his channeling only lasts 1 second so it has a higher rate of sucess compared to Malz.
Cant deal damage to you while he ultis you so he basically just holds people down, while allies punch him and you know you have to actually catch people out with it
Cant damage you beyond his values as you are sheltered from your enemies for the same amount a Morgana binding works and you know your a melee like skarner so devouring enemies takes some creativity.
Here is the kicker tough, 99% people never consider using QSS (as it has a popularity of 1%) even tough there are crowd controls such as
root(3 seconds) which is a fire and forget spell. Yes, it gets reduced by tenacity, but people who would build
would never build tenacity, because they need penetration or attack speed.

exist and are "kept in check" by that rather than balancing the numbers where this item doesn't exist.
