As the game progresses I would expect the trend to continue of enemies getting better defenses. With that in mind, hard CC will start to be less of an issue from our side as well since only one or two enemies will be vulnerable to it at a time.
The real issue in my mind is whether or not bosses need something to aid them against CC. Currently I'm leaning towards not, but if they had a buff that made them immune to CC for one turn after getting CC'd I think that would be okay.
