How Should Infection Be Added to Matchmaking?

Infection appears to be of much debate lately when playlists are involved. My question to the people of Waypoint is simple. How should Infection be added to the roster should it someday be added to matchmaking?

Of course, the playlist would be cross-game with Halo 3, Halo 4, and H2A being the games in it, and it’d be unranked. It’s a simple question with a lot of power for it’s fans.

I feel as though it should be merged with Action Sack personally.
