2h stab animation RANGE was nerfed. It allowed 2h to act as a pike before, now it doesn't.
But now, the 2h stab is an almost animationless, instahit attack. The hit registers almost the moment you release that attack. Which makes it messed up in a different way.
Yeah, an attack doesn't have just one "Goodness" stat that is either nerfed or buffed. Incredible, huh?
