I saw this guy chasing an archer and glancing 3 times in a row. He didn't look like he was too close or too far, it just bounced off really oddly. I think the glance rates should be tweaked for the further extent of the stab with or without shield, so its a guaranteed hit if you reach long enough. Even if it does less damage its better than a glance. Especially weapons with 2 attack directions, with 1 doing like 18 blunt.
It glances when the weapon momemtum isnt enough to cause damage : too close and the animation didnt begin (no momentum), too far and the animation is over (no momemtum).
While one can argue that the 1H stab can hit at very close range, and hoplites cant, and I think they should too (even more than 1H, because they dont have much attack directions); the glancing at the end of the animation is normal.
P.S.: new patches please.
