It would be so good if as a predator you were able to parry, block, and doge. This would work for FT to, but would be less powerful for FT. It would make fighting more fun.
They maybe could even make a bullet block, but runs out of Stan = No block. It would make melee combat take skill be more rewarding to do so.
Since there is so much melee weapons than ranged it would make some of those weapons less useless. They could even make some useless weapons like war club have a good break block or the battle axe knocks down an enemy who doesn’t block an attack.
I don’t know if this would be good, but sounds like a good idea and plenty of people have already said stuff like this.
