I'd like to bring attention to ever forgotten and equally useless vehicle, the Enforcer.
About a year ago I suggested some changes to health or projectile resistance to make this slow vehicle somewhat useful, while that suggestion never made it through I came up with this one; higher number of possible players in the vehicle, increased passenger limit.
Even something as simple as /cargrab but with players appearing on the inside of the vehicle, or DE style command for sitting in the back of the Barracks would do the trick. Since glue is now nonexistent, it seems like a great time to give Enforcer the function that it was designed for - Transport!
It looks too cool to be left so useless!
