I have enabled with Multi-Mode plugin for the server. It's still in testing so please bear with us and report any issues that arise.
It has been noted that when map changes occur, players may end up on one side or another for multiple rounds (2 rounds as defender or attacker). This is being worked on. Hopefully the changeup between Rush and Conquest modes will be enough to break up some of the monotony of this issue.
Let me know what you think and whether or not it should be left as is, dedicated to one or the other, or have a Multi-Mode night once a week.
