It's an interesting idea but it leaves a lot to be desired. I think the 4v4 style doesn't work that well in a melee centric game because the gameplay will end up being "get to the spot we need to cap and brawl." It works better in a shooter because distance adds the needed depth to the gameplay. As a death match style game, it would work better.
Character designs are also lacking.
