Thanks for the advice, guys, much appreciated.
I do have a habit of wading into the enemy (usually after getting over the top of a ladder in siege mode) and just swinging madly because I know no teammates are near me. I am too slow to body block them, unfortunately. :-( And you know how it is, the enemy's a good player and blocks the guy he's fighting, then makes to attack him and suddenly leaps out at you instead because you're waiting with a swing ready and are trying to move around your teammate. Even when I can see that coming a mile off, it still normally gets me because I'm slow and I can't flipping block. >_<
Good advice though, all, I'll try to employ it.
Merry Christmas!
