Most irritating glitch for me is the ghost blocking... See enemy do overhead swing, quickly do upblock, enemy swings and you're dead. Huh wait didn't I just block that hit? Not according to the person who killed me, but on my screen I had my weapon held high above my head ready to recieve the overhead.
Before these comments come in(they usually do).
I'm not talking about crushthrough weapons, although it happens with barmace alot it's mostly 2h swords that go through my blocks, sometimes side blocks but mostly overhead ones.(Enemies attack does not register your block atall).
Happens in circumstances where the enemy is directly infront of me and not strafing to the side or trying to flank me.
Another issue which is less common.. Sometimes when I ride my horse around and engage in fast paced lance action vs other horses, sometimes it feels like the server can't keep up with my characters movements and sometimes I lose all control of my character and it kind of teleports and stutters for about 5 seconds in which time I could be killed or ride into an enemy zerg and won't be able to do anything about it.
