A simple idea for multiplayer. A setting which when enabled automatically replaces your current weapon with a preferred one on the same slot, if that's nearby of course.
Basically the following scenario:
CakeEater234 picked up Alien Pistol. CakeEater234 has this setting enabled and Pistol C-01p is set 'preferred' for Slot 1 because the other pistols suck. CakeEater234 steps on a Pistol C-01p. Alien Pistol is replaced with Pistol C-01p.
You could set weapons for other slots as 'preferred' too, for example Shotgun C-01s as slot 3 or Assault Rifle CS-RC for slot 2.
However, you wouldn't need to adjust it for all the slots. If you, for instance would say that 'I don't care which railgun I get' then you could leave that on 'Default', which means weapon preference wouldn't work on slot 4.
I don't see any negative sides of this. Any thoughts?
