aCookie, I propose that you add some type of parkour or something to get out of the arena once you are in it. Otherwise, it just turns the arena into a deathtrap that you cant really get out of unless you have other people in there helping you.
/warp pvp is meant to be a death trap And all u gotta do to get out is /spawn Or log out for awhile (make sure your outta combat)
It is quite simple to get out of /warp pvp, Just remove your combat timer and do /f home, /home, /spawn or whatever. because usually when your finished in battle your the only one left
