Headsets and Vocals in Rock Band 3
I already know that you can't sing with headsets in Rock Band 3 because it would mess with the harmonies, but that leaves me wondering: If there's the headset port in all the instruments (Or most of them), why can't there be three headsets instead of three mics? It seems to me that, not only would that make it easier to sing and play an instrument, but, with a little implementation, the characters in the game could sing the part their player is singing instead of a random harmony.
These are just my thoughts. I know I would like such an update in the future, but if there's some flaw in the idea, let me know.
