It doesn't matter what imaginary rules you make up for a map. I am allowed to use ANY gun I want when i want. Oh and i don't have to sit out on the map if I don't want to. Have a nice day.
Shipment isnt even in the active map pool. An admin has to directly intervene to command the server to change to that map. If the rule while starting this map was to use only shotguns, then you deserved the kick.
All else fails, obey the admin's request. If you feel the request is unwarranted, demo the discussion (press your Tilde key "``````" to open the dev console, then type /demo admin)
Inform another admin via our website and share the video. We manage our own, and dont allow admin abuse of any kind.
