Remove Pistol from Assault

I don't know if anyone else has found this kind of awkward when playing Assault, but it is annoying that my 2nd primary is bound to a gadget rather than being just another gun in place of the pistol. Would rather just have no pistol and 2 primary guns so I can quick swap with the more natural input.

It is nice to take a longer range DMR or Carbine and having the shotty in my back pocket but the instinctual button press when trying to swap weapons in some heat of the moment fights leads to me whipping out the lil weak pistol when I forget my shotgun is my "gadget". Having the Assault class as a dude with multiple strong weapons with limited ammo I kind of vibe with, need to make use of all those guns if you don't have any resupplies, and when you got a Support you can both just rock together. I think we're gonna see some things like gadgets move around between Support and Assault so we'll see if it stays this way or totally change at launch.
