RNGless CC is the best thing a strategic game can include. As soon as there is rng for something really important it becomes luck based -> bullshit
I would be more into the camp of RNGless CC is bullshit.
100% chance to apply CC, no defense what-so-ever... it's insane. Have you tried how easy it is to CC opponents in D:OS2? With 100% chance to do so, there's literally "STUNLOCK ME" written on all opponents. I hardly find that emergant gameplay. Why do damage if you can just permanently take them out of the game, no questions asked.
There is a defense, it's called armor. You do damage to break the armor. The enemies on the EA map are a walk in the park because this is the first map. You spend half of your time on the map in trash gear that's been pieced together. The enemies can only be so strong while still being within the realm of reason.
Furthermore, Tactician Mode isn't in the game yet. All we have right now is basically the beginner map with a highest difficulty of normal. You can't really expect the enemies on the EA map to be an indication of enemies later down the road. I would expect to see enemies that are more heavily armored in later content.
