Say RED has no sniper. I'm a BLU spy disguised as a RED sniper. This means my apparent nick will be determined at random. IIRC, I might even get my own nick.
What about my loadout? Will I be using weapons at random? Will it be taken from the appropriate loadout of the nick I'm using? Will I be using my own loadout?
Say I switch to the pistol and press B (use last disguise) and I get a sniper rifle. If I switched to the knife, pressed B, then back to the pistol and pressed B, would I stand a chance of getting a more believable huntsman instead?
