When hitting a door you usually do overhead swings, and usually very close to someone else. So I try to stand still, not move my mouse and just swing. It will usually do overhead swings. But every once in a while I do a right or left swing... Sometimes several times after each other. I've hit friendlies enough times, and even killed once, to know that I should just stay the hell away from doors and gates. I've tried moving my mouse up during every swing, but that is difficult do to without accidentally moving a bit to the right/left. So is there something special I'm not getting here? Or am I just not good enough at holding my mouse still? I've tried it in campaign as well, with no distractions, but it still happens...
Also, as a 2H user. I just get owned by people with hammers since they hit through my blocks (I'm guessing that's what crashtrough is, and I see only the Maul, Mallet and Great Maul has it). I keep my distance if I can, but in tight hallways I don't stand a chance. Any suggestions? Kicking maybe?
