The other thing is... when the X-Men go for the final battle, how do you think it would have been to have Angel approach the X-Men, and ask if he could go along with them, since his father is on Alcatraz? He did overhear them, he knew they were going. It would have been great if he could have become a member of the team for the final battle. It wouldn't have changed too much, he still could have just saved his dad, but it would have given him a chance to be A.) Part of the team (as he was heavily advertised in his costume), and B.) Give him a chance to kick a little bit of ash in the final battle, make him a more useful character, and give Angel fans something to cheer for. And it would have given a bit more payoff for the introductory Angel flashback scene, as well.
* Well, we wrote that exact scene. But it didn't make it past the powers that be. There were actually some legitimate reasons for this having to do with production restraints, difficulty with the wings, etc, before everyone starts lumping this in with the Scott stuff.
