I would like to make a suggestion. It's something that is in different games already, but I think it can work in MWO aswell.
Would it be possible to make a spectator and a tournament mode for MWO?
The spectator mode will allow a player to look at 1 player in the game, this player must be on his/her friendslist and the person being watched must give permission to let a person spectate.
Why I suggest this is so people can get some coaching from a friend that has been in the game longer. They can be given pointers and tips. The person that is spectating cant chat in the normal channels (all/ team/ lance). He can however chat with his friend.
The second suggestion was a tournament mode. In this mode you can invite 16 players, 8 on each side (or more when the maps grow bigger and the teams grow bigger). After inviting the players one side may select the map where they want the play on, after that mechs will be selected and the game can begin.
In this mode you also have a referee position (you make more of these so more people can watch the match and be referee's). The referee's can chat in all and a special referee channel but cant join team or lance chat. The other thing the referee can do is spectate with every mech in the game. (I think its clear that this would be very interesting for tournament in the future

The referee would always see verything that happens, so they arent botherd by ECM or buildings (this is for casting ofcourse).
In the end a overall view could be implemented, so the referee isn't bound to the spectate mode but can also hover over the battlefield to cast what is happening.
I hope you guys like the idea.
