RNG plays an important part in games - it creates variety within the situation you can face. However, RNG shouldn't affect your ability to deal with those situations, which is exactly what happens when the CC is RNG based. So, going back to the old system isn't really a good option.
Nothing is really based on RANDOM numbers.
The chances of success which are percentage based are not - random.
If you have 90% (or any other percent) chance to do something or defend against something... it. is. not. RANDOM!
And the player can affect these odds and chances by building the character, choosing his or her stats and abilities and getting better equipment.
So in actual f`ing FACT - the problems with current implementation of both armors and some status effects can be solved if they are percentage based. And if the Hard CC effects are changed into softer effects.
There is actually no "rng" to it. At all.
Because its not random.
