I would like to suggest a gamemode called, 'duels' because this gamemode is by far very big on >edit<. This GameMode is a 1v1(with Elo Ratings) with a lot of different kits like Nodebuffs, Gapple, Diamond, Axe etc. I think MV will pick up its players back when this gamemode is inputted. This Gamemode is fun, quick and requires skill. No Support, Support
Neutral, the reason some servers have this is because they are pvp dedicated. We're not. It is a good idea though, and it's fun. I just don't know if this will make such a hit like it does on pvp servers.
No support. - We do not have a top-notch anti cheat system right now - We're not exactly PvP based/dedicated, as Reborn mentioned - We don't need too many gamemodes (like e.g. Hellblock that's totally deserted was once a busy gamemode) that will be a hit when it's first released then become extremely deserted and abandoned after a few weeks.
People saying "not pvp based or dedicated" yet 6 gamemodes are heavily pvp based. Like kit, op, skywars and infection which are the most popular game modes.
