Armour only reduces physical damage, which is really the least worrisome type in the game. You pretty much got Evasion and Leaves Tide type % defenses as the only reliable-but-not-perfect-like-Unstoppable option that will scale past Normal mode into the higher modes. That is why only a few classes are viable in the higher modes by my understanding. Ranged magic damage is the most deadly type to deal with, especially in the higher difficulties.
So basically what you are saying is that we just skip tome mechanics because no one is willing to touch it and replace it with dumbed down version where simple % checks will determine if you live or die. Lets take a look at your skills
Disarming Feint - solid skill. Not particualry AI firendly but from time to time mobs might surprise you and use infusion instead of attacking you

Deadly Riposte - Why would you add critical hit to skill with such a low cooldown ? It breaks default mechanics and ofc your guaranteed critical hit could be shrug off because some other skill guarantee that all critical hits do in fact normal damage. Why would i invest in dex, heavy armor training, gear when only skill can effectively counter other skills ? I know we already have assault and imho it is a poor skill. Sure it is great when you attack mob for x dmg but it is kinda bad when despite all your efforts you get critically hit just because some skill says so
Parry and Dodge - simple % check replaces everything else. No way to counter it. If you make stamina cost low it will be op. If you make it high people wont use it. Most likely at some point someone else will add different talent that affect stamina in such way that your talent will become op anyway

Fearless Bravado - improves your odds during simple % check.
3 of 4 talents require special, alternative mechanics that doesnt interact well with gear, stats, other skills that boost or reduce 'old' stats like accuracy, defence.
