The argument of "it gets less tactical if RNG is too strong" is pretty much void of meaning, there is no correlation there.
Divinity 2 currently has no RNG on crowd control and there is absolutely no tactic required on the combat part of it. There are too many ways to reposition and whoever is out of armor will be stuck on permanent CC.
In a game with a strong RNG luck is as important as tactical decisions, because your perfect plan can be ruined by a single dice roll.
It is great that the crowd control abilities of DOS2 have no RNG, but you are right, that they do not have much tactical depth, because the armor has to be removed first.
