Xbox PvZ GW2 Tournament

I recently started a tournament on Xbox for PvZ GW2 but came across a problem in matchmaking. I would love to see a change in how many players and how much control a player has over the match. There should definitely be more than 4 players allowed and team should be able to be a lock. I know the community would love this and it would be a very minor patch. Please take this into consideration.
