It would have to be 4v4v4 18 players is unsupported on Last Gen consoles

Lame for making up an idea that's been asked for

It's not viable because there are more hunters in crucible. Let's say there are 100 Guardians: 40 hunters 30 warlocks 30 titans (this is approximately the real proportions) You'd have 5 full games, and then 10 hunters sitting out. That's 25% of the hunters. Let's say an average game lasts 10min. That means the unlucky 25% of hunters would have to wait 10min. BUT obviously all games don't happen at the same time. How do we adjust for this? Simple. We divide the 10min waiting by 4, spreading it over the whole hunter population, getting a 2m30s wait time for hunters provided there was some sort of queue system. Since some lobbies will stay intact after the game, new hunters joining matchmaking would face even longer wait times. TL,DR: It wouldn't work because Hunters would have to wait on average an additional 2m30s for matchmaking to put them into a match. The only solution that comes to mind is a restriction preventing an excess number of hunters from matchmaking in that mode. Edit: Cool idea though

Wow you people are lame. It would be fun to have a mode to play on teams against other classes.

How bout no

Let's stick with more PvE modes.
