Suggestion for Ascension.
In the game mode ascension with the sheer amounts of random skirmishes and lack of vision Crowd Control becomes a very toxic mechanic to the point it seems whoever has more cc wins. You could always say build QSS but the long item cooldowns don't help with the rapid fire fights and low cooldown skills.
I propose a global passive, kind of like with Howling Abyss and URF whereas either "item cooldowns have 40% cooldown reduction" but that would open up everything not just QSS. Or "Crowd Control has X% reduced effectiveness/duration(Excluding slows) on the Crystal Scar" I think it would make the game mode healthier and less Anti-fun with heavy cc comps.
