If we added the vanilla damage system everything would be broken. The only way people would die is if their armour broke. Which doesn’t happen. (Tested)
Why? Your hitting an armoured player with FISTS. Fists are made to do nothing while your in armour. Like hey I’m gonna punch iron or diamond armour with my fists and expect it to hurt this person or dent their armour.
You should at least hurt them by a little, since you won’t be able to do anything to an armored player rushing you if you just respawned other than knocking them off if they block your echest and generator.
It would also stop spawnkilling to a certain extent.
