CC that relocates enemies

After thousands of ranked matches, here is what I have concluded from observations. This is not scientific, but perhaps it lines up with your experience too.

Crowd control that stuns and knocks back champions or moves them to a different location are considerably more powerful then a simple knock up or stun.

For example, Gragas Ult or Voli flip. It just screws the enemy up so much more. Champions like this have never really ever been considered bad picks or under powered or not useful. Crowd control like this will always be very strong no matter what changes are made to the game, or which champions get buffed or nerfed.

Some champions have kind of CC PLUS other CC. I think those champions are over whelming overall.

Do we not all groan when we see Gragas or Voli as junlger? We never go, yeah no problem. We know they can definitely be a problem. More than numbers, does this experience indicate that these champions are better and more powerful in more team comps than other champions?

I think so. I think Riot does't know how to value crowd control vs other strengths a champion could have. From all the games in the last 2 years I have played, this is my conclusion---League of Legends distributes CC among its champions in a way that ensures certain champions will be either OP, or at the worst, still very useful and decent, no matter what changes in the game.

I'm not sure I really like that.
