With current CC conditions it is not a good idea to make it random. They are too strong.
This is good. And bad too. Currently, cc's in the game are extremely overpowered. They took entire turn or even more from the character.
Maybe it will be a good idea to make cc's weaker. E.g. stun removes 1-2ap per turn, silence increases cost of all skills by 1-2ap, and so on. Make it "soft" cc, not "hard" ones. Maybe, make it last several turns instead of one-two for compensation.
