Personally I think the dashing about back and forward thing looks stupid, heh
I suppose it comes from playing Neverwinter Nights, but to me, beating someone is done by having a higher weapon skills and more powerful weapons, not by trying to time your key mashing.
Which brings me to another point, I fail to see how it's possible for that to be effective when I've heard even people using broadband get a ping of like 300-500 in this game. How can timing be effective when you're 3-5 seconds behind what's happening?
