was running a long time with the intelli mouse than had a razer deathadder for 3 years until the left and right mousebuttons died and now i have the steelseries kana, all wery gud.
i think the quality of the mouse in terms of dpi/accuracy is pretty irrelevant for wot since you don't need any aiming skills. try a few of the mentioned in store and take what best fits your hands.
personally i never liked logitech mouses because they felt awkward in my hands, but that's just a matter of taste...same with nvidia/ati gfx imo
