I've been doing a dual lone wolf playthrough in OS1 in between testing OS2 and providing feedback and I can say that CC is an issue in both games.
If you have higher initiative and a lot of CC, it's basically a free win. The enemy will be stunned, knocked down, frozen, etc, while you beat on them, buff yourself, and while the CC skills you JUST USED move towards being off cooldown allowing you to use them again. It's incredibly cheap. Even with 2-3 people I've found I can CC everyone fairly easily in OS2, and then annihilate people with my warrior while they're helpless.
But it works both ways. We only have one act so far, but since the system is fundamentally the same, it's the same as OS1 insofar that, if you have shit initiative/are facing a lot of enemies/don't have a full party, you are entirely at the mercy of CC. You can find all your characters disabled in the first turn and then you get to just watch yourself die as the game plays itself. Not good, and makes harder difficulties/something like an ironman mode an exercise in frustration and cheap CC exploitation from both sides.
Honestly, aside from a couple of 1 turn disables, I think most CC simply needs to be changed from hard CC to soft. Don't disable people; gimp them. Frost can kill your movement, shock can kill your accuracy, etc. But either us or the enemies being helplessly beat on is bad. It was bad in the first game and it's bad now.
