Warrior’s Greatsword skill Rush has been broken since the 1st mode patch.
Bug: player rushes in reverse (back instead of forward) when cast.
Since it can’t be interupted it’s a gamebreaking bug as you can rush in directions that cause death.
It happens mostly in first person mode, but tends to happen in third mode a few times as well. I cannot guarantee it’s caused by the 1st mode patch, but I don’t remember having this problem since before then.
