Funny thing is, it can be argued that the X-Men *don't* work very well without Cyclops. What happens after Scott leaves? They decide to team up with the Hellfire Club, they get their hinders kicked by the Marauders, and then they have the brilliant idea to let the world think that they're dead while they live in Australia.
Other writers have used the idea that Scott is somehow totally worthless (or at least thinks he is) without the X-Men. Joss Whedon used it in the "Torn" storyline in ASTONISHING.
