"Fuck you"?
Really man?
The situation you wrote is only possible in an alternate universe. There is absolutely no way of knowing what would've happened. We wouldn't have I&W or Awake or SFAM, who knows?
We don't know the extent of their involvement in the band's writing process, since that's what a band is, a team, which is a combination of everyone's efforts and creativity, not just one individual.
ADTOE is a fine example of this, since, as far as I know, it was 90% written with only 4 members, no drummer, and yet it's still a very fine piece of work, much better than MP's last two albums.
