A valuable, yet simple feature to implement into Halo 4’s custom games would be the ability for a party leader to change and lock any player in the lobby’s team.
We’ve all been in a lobby when we want plain old RedVsBlue Slayer, and people continually mess around, choosing Brown and Gold teams, etc. It is a feature I have wanted for quite a while now. Thoughts?
Hell yes.
Yes we need this
Hell yes! And perhaps, even allow the party leader to determine the teams.
This feature really needs to be put in Halo 4! I can’t count the amount of times I have had difficulty creating the teams in custom games. Good Idea!!! 
Any ideas for elaboration on the feature, i.e. how it would be implemented?

Comin’ from the guy who hosts a million custom game lobbies and created half my maps team-based. Yes.
Team leaders? PL makes some one a TL, and they can request to the PL to have certain people on their team.
Think back to those schoolyard games, where two people picked the team for whatever you were playing?
If this doesn’t make any sense, blame the fact I’m doing this on my phone.
