In kitpvp, when you need to change kits, you often either ask to get killed or relog, but i suggest adding /respawn. /respawn clears all your kit items, but leave the mystery drops and stuff respawn also teleports you to spawn, and once you select a kit, you get all the kit items, but still keep mystery drop/fishing i tems. You whould need to be out of combat for 20 seconds before using /respawn. This would make it so people dont run away and /respawn to get a new kit
