i agree that the thrust stun is a little overboard, especially when you thrust a shield and get stunned for it. though I think 2hand stab is fine damage wise, and hoplite stab is simply a little too high in comparison. hoplite now is basically dedicated 2hand lolstab class, but with auto blocker and 5+ higher pierce damage on most weapons. hoplite had shield penalties reduced or removed to "compensate" for the thrust spin nerf, but everyone has since adapted to aiming so they feel overbuffed now.
I also think all weapons have stuns that activate too early and create the illusion of "instant" attacks that defy common sense, makes chambering very difficult, and frankly create nothing but unfun scenarios. I like the change from spin stabbing to easier to land but less pivoting stabs, but it feels buggy and awkward as it currently is done. backpedaling long polearm users make me rage more than ever before when they land nonsensical stabs, and 2handers seem to be able to spam the thrust way too much to interrupt most other attacks as well.
