The problem with MC is that they want you to play with other people, but instead they're making the Open harder for Solo players, forcing them to stay in Solo.
Please not again the "open will die" mentality, open players will stay in open, solo's in solo.
Some open players will go solo and the other way round if they have friends to cooperate with.
I don't see open die and I don't see all solo's changing to open. People are people and they will play how they enjoy it the most.
