I think you guys are missing the point.
I'm not saying make it completely random like you guys think it is.
After you reduce the enemy's armor to 0 you basically have the current iteration we have right now, save *maybe* multispecced characters not being completely reliable.
The propositon is to add chances in case you want to take them, and that's it. If you want to blow a CC a turn early for a 70% success or wait for a couple more hits for a guaranteed 100%, it's still there.
The system wouldn't force randomness on anyone.
I proposed the exact same few days before.
Barely few people read, answered couple, non get the core idea.
So I am to going scream with you :
Option to take a risk is advantage.
Option to work on strip armor then apply a permastun
OR
Option to take a risk and try that now.
Also, the 2 kinds of armor should be rather 3 connected to 3 main stats Str,Int,Dex. that way you get Reflex saving throw for traps, lighting spells, knock down and so on. e.g. you would rather Knock Guick silver rogue or a clumsy mage? Those kind of decisions are missing in current system. Strip it and knock it. No matter who is it, no matter what skill, attributes or whatever, still the same way to deal with it. So it feel boring and plain.
However, option to save in combat should be changed like, if you save in combat you load on the first round.
