I just don't think CC is interesting, that's all. Again, just my opinion - I'm not saying I'm right. It's a video game, we all have our take on it. For me, CC has always been the weakest link. It's not imaginative, since it just stops you from having to think (you can't think with a character who can't do anything).
I'd rather CC punishes you in some other non-restrictive fashion. Other people have made many good suggestions for alternatives. Stun could cripple your ability to move, for example, but you could still fire an arrow or cast a spell. You should always be able to think, IMO. And do something. If the game prevents that, you're not playing a game - you're just watching a screen.
