The only way we could disable it is if we have a map editer, and since there isnt one around its a no go sorry.
I think it is a fun part of the map so I dont see why you'd want it removed, Helps with those bosses with an ungodly amount of health (Team Killer, Nopegineer) Plus Not a massive amount of people know about it.
If the buttons pressed and a player dies in it then I guess its just a case of Wrong time Wrong Place.
