You have such a hate for two-handers. I've never seen someone complain this much about a game mechanic.
You are right, I don't think the devs will remove the two-hander "lolstab" since that is a complete game changing mechanic and I assume most 2handers would rage really really hard.
So, following the rules of Utilitarianism, majority happiness > minority happiness- which is crucial when running a gaming community.

They have nerfed it really hard though, and it does glance a lot. I think that every time you get stabbed you rage, but you neglect every time the stab glances off you and so don't take an accurate account of successful:failed attempts ratio.
I could be wrong though. And you could be the unlucky player that gets hit by every single 'lolstab'. But I know, as a 2hander, if you don't time them correctly your stabs will glance.
