I'll leave the silly illogical arguments around this one to the others.
I'll simply say yes it should be available to join a MC from Solo or any mode. I am not going to change modes just to check a queue & certainly not going to sit in a mode waiting for players. Same can be said for CQC, which is why I don't play it anymore. At the very least it should show you what ships are MC in Solo so I can choose to change modes if I so feel like it. Most MC videos I have seen has been against NPCs anyways, not PvP so why limit it to just Open?
