I think i would be loosing out.....
i dont like to waste ammo, i like to get close (very close) to my target without him knowing im their, then open up. Im that close that im pretty much gauranteed to hit. So being able to choose between different weapons would help. In that situation i would just choose the cannons and save the MG's for when my cannons are dry.
So i would like the option of my joystick being able to select between dif loadouts
IF it wont happen then its no big deal, im quite happy with all guns firing as it is at the mo. My main concern is other issues gettig fixed such as the crashes and the P51
