Below is an Interview Q & A.
Interviewer ask:
Clan support was a feature that got many players into the competitive spirit of Halo Multiplayer in a challenging-yet-rewarding way. Why has this feature died, or rather been missing in action, since Halo 2? Was it ever considered for implementation in Halo 4, and what was the deciding factor in it not being included? – u4iX

Social constructs are something we too have missed since Halo 2, and we’re looking at interesting ways to improve those experiences in the not-too-distant future. I will be using that expression a lot. Get used to it.
