I have noticed that since Halo 4, the multiplayer seems very hostile to the idea of meeting new people. The way the lobby system is in Halo 5: Guardians is very anti-social. I cannot see the names of the players I am playing with/against until the match starts.
I would like to see the lobby system improved so I can see who I am playing a match with and I would like to see which player is going to which team before the match starts. This would make it much easier to coordinate gameplay and call out players in the match.
Another addition would be the return of the players staying together to match again like Halo 3 did (I think). This would make it easier to keep playing with people you got along with and build future connections with.
All of my Xbox friends have been met either in real-life or by Halo multiplayer. I want to expand my horizions so I can meet people who love Halo like me. If 343 Industries implememts my suggestions, this would strengthen the community and encourage players to be more social.
