Just tried out Private MP Lobbies this past weekend with a group of friends. We had many issues with the system that is in place for Private lobbies.
If there is a Host, that host should have Full control in the lobby of what maps and game modes are chosen and when they start up. The voting system and countdowns is not needed in a Private lobby. Everything went way too fast and as a Host, I had no idea what game maps or modes were about to be chosen and played. I don't see how you'd be able to pick your own map to play on it with a group. There was also no down time for breaks and chatter between friends. As is, it is not a viable option for our community nights. Which is a shame as this has massive potential that isn't being seen right now.
It was also a bit of a challenge to get everyone in the same Lobby. What wouldn't I be able to bring my party with me into the Private lobby when hitting 'X' (on Xbox)? I would have to break apart the in-game party, then start the Private lobby and talk them all through putting in the password. Not intuitive.
Lastly, we really need more than just TDM and Death Match to play with groups larger than just 2 people. With such a robust map editor, there should be a plethora of different kind of MP modes that are geared for groups of 4-12 people. Please bring us more modes that can be fully customized with the editor.
Thank you for your consideration.
