Sir_Giggles said:Yeah you could, but you have to stop momentarily to switch weapons, especially when strafing right. And with button 2, you can bind it to a grenade launcher, while you use button 1 to shoot rockets.
Not a meaningful problem. Trust me, I've gamed with this configuration for about five and a half years now, and one would be hard pressed to tell exactly when I switch weapons. Furthermore, it's not difficult at all to reallocate the fingers on your left hand such that you're still moving. Say you're moving forward and right and want to switch to your next weapon (the worst situation). You just slide your fourth finger to W, your third finger to D, and use your index finger to hit R. A maneuver that isn't at all difficult to perform (barely more difficult than scrolling a mousewheel, and about as difficult as scrolling a mousewheel without also clicking it while under duress) and takes a fraction of a second.
And I'm not seeing your point with the grenade launcher. If you've got a key or button, of course you can bind it to something while you use another key to do something else.
