Basic idea bring arena back for short periods of time once a year.
Fixing the problem of low player numbers, wasted sever space making it a limited time thing. As well as lowering the load of maintaining the game mode through out the whole year with game updates.
Could also so tie in streamers to this event such as a doing a tournament as the finale nearing the end of the event!
i all ready got the blue hat but miss the days of arena.
