This is so beyond abusable that it's ridiculous.
Someone could easily walk into another base and unleash hell without being damaged upon entrance.
Someone could event a huge explosion brick right next to another base without being killed.
Someone could trap other players with no danger.
Someone could drive around a tank and be unkillable.
See why this is a bad idea?
1. How could somebody "unleash hell" if they can't use a weapon to stay invincible.
2. Events can be disabled and kind of should be disabled anyway for a fort-war.
3. If a player gets trapped an admin can kick them for trapping or delete the trap. This would also probably only happen if the person was afk.
4. Didn't gravity cat make a script or something that disables items from being usable in a vehicle?
EDIT: Also if somebody is in a tank, they can't shoot the turret without having the brick placer/tool un-equipped. Firing the turret forces a person to unequip anything.
AND the tank can still be destroyed if they are just running people over.
