Hi, I was wondering how good/bad the World of Warcraft Gaming Mouse Steel Series would be for online fps shooters like battlefield 2 and call of duty? I like the way it looks, it seems comfortable for the hand and I know where to get it for $25 but I hear a lot of people saying it sucks. Also it's apparently designed specifically for World of Warcraft which I do not play. I want it because of the way it is built(it's thumb and pinky rests look comfortable) and to play fps shooters which it is not "meant" for. Am I going to be disappointed? Also does it have "on the fly" DPI switching? very important to me(in fact most important feature of all in a mouse to me).
