Am I the only one who thinks that spamming cc guarantees you free wins?

Well... maybe not always but I've noticed that if you have a team composition which has a ton of hard crowd control (for example Sejuani , Leona , Varus , Sion , Morgana ) basically you can steamroll the enemy team with so much crowd control that they simply can't fight back whilst you rain down damage on them, making victory in team fights almost guaranteed and ultimately the game.

When this happens (and believe me it does)... how's this supposed to be fun? I understand that crowd control is part of the game but the way things are right now allow this to happen. I'm pretty sure nobody likes being made to feel like he has no chance to do anything to defend himself and just die like this and I'm pretty sure we can't give everyone Gangplank's oranges to address this...
