Triple post because... Dunno...
I'm thinking about removing Rotondo's L4B shoving. It gets abusive and is annoying to moderate. The shove also means weapons such as the Sniper Carbine, MGs and whatever other weapons that require a right-mouse-button function don't work properly.
To balance this out however, I'll introduce melee weapons such as knives, bludgeons and pointy things.
To stop melee weapons from being over-powered and ultimate tanks, I would remove Rotondo's shove.
So you have two choices:
Remove shove, introduce melee weapons.
Keep shove, no melee weapons.
This could also introduce spawning with a weapon.
