Some weapons just need balancing so they can compete.
Pistol needs more damage.
Pistol is very accurate. Make a few headshots and they'll drop like flies.
Crowbar needs to do 30 damage.
I could be wrong but I believe hitting them in the head does more damage. Overall crowbar is a back up weapon and shouldn't be used to chop down people who are shooting at you.
HUGE needs slightly less spread or recoil.
The HUGE is still a room cleaner and by far THE weapon to have on low to medium range. I wouldn't buff it, nor nerf it for that matter.
