Nerf Glacial/CC

Why has riot not nerfed glacial? The fact that you can stun lock an entire team with no chance of escape is unreal. Some possible solutions here so I don't look like a complete smuck:

• make it have a per champ CD
• make it unstackable with all other forms of CC (i.e) if you freeze a champ/all other debuffs are removed
• building on previous/if they are under a current debuffs foe champs can't be CC'd
• make all glacial champs blue or higher (and buff lower accordingly. (Should remove the early game dominance and late game difficulty)
• make the glacial debuffs either a atk speed reduction or just a root. Not a full stun.
• Cut the stun time in half
• Make it a flat stun rate but increasing stun times.

Sejauni specifically- death negates channel/on hit AOE/ maybe a on hit passive after 3 hits like vayne.

Or overall for the game make hard CC have diminishing returns or stack results. I know I sound salty: because I am. I really am. Just tired of losing to a glacial team with a roided out Ashe on the back and sej on front stun locking everything. There is only one item to counter it and even then it's once every 5s. Hardly a counter. I have heard people say oh just kill them faster or some stupid shit. Yea I had not thought of that at all, not once did I think that. If I had more control over targeted maybe but that's just not how the game works. Especially when by stage 3 you can pretty much have it all together, RNG be damned since I have yet to play a game where there were not at least 3 people rushing this crap.

All I'm saying is, RIOT look into some way to change this because it's not fun to lose to this not in the slightest.
