I'm not saying I mind, or that I'd be bothered if they expanded it. It's more I don't see the point, and I certainly don't get the frothing rage you're offering up.
I would
love it if they:
- Did it for all future tracks
- Allowed three guitars (Lead, Rhythm, Bass) even if they kept it at four players only (In fact, I'd insist)
- Didn't detract from the current guitar tracks
- Didn't drop bass as an option
Otherwise, I'm not against it, but I'm not really for it, either. I wouldn't complain, though.
