Of course you think the mouse is making you better, before you didn't have a mouse.
If you're good, you're good. 20 dollar mouse or 200 dollar mouse, no matter.
well, when you can get ur frag grenades off in less than a second, and u can switch to ur smg in the next second, then light up ur opponent in another 3 seconds, it makes u a little better =P. for toribash, i was using a touchpad previously, so there is no doubt my gameplay has improved from this.
LOL, when u have to hit the 4 button, then throw 2 grenades, then hit the 1 button, and pull out ur SMG, light up the closest enemy, then switch to ur sniper, and lower ur mouses sensitivity for maximum control, snipe the enemy, it would take longer than 5 seconds if u were using traditional tools.
