Feedback for duel in general
-Should be a matchmaking queue option with an elo, not a custom server
-Should be first to 7(Community standard since... well forever)
-Should be a "duel faction" only with one class selectable that has access to a 1 and 2 handed, sword, axe, mace etc
-As per above feedback by Killfacer just make the arena's flat and small
