I'm having serious issues with swapping profiles around easily. It's a pain to sign out just to switch instruments and then sign back in. How about a start menu that looks like:
Selecting "Switch Instrument" goes to:
Switch With Player1
Switch with player 2
That would make it so much better. As it is I cannot use my character while hosting an RB party as it is too much of a hassle to switch instruments constantly.
Another bug with this is trying to "Swap to XXXXXX" doesn't work all the time. Sometimes it just leaves the players as they are.
