Yeah! And you know what? How come the Fellowship of the Ring never fights together after the first book, either? They get split up, and Boromir never gets rezzed, and then Aragorn has to do the whole Helm's Deep fight without the party rogues.

Also, you know who else? Star Wars. I mean, every fight, one of them is deactivating a tractor beam, or training on Dagobah, or blinded by carbonite sickness, or piloting the Millenium Falcon with Nien Numb. They're never all together in one room fighting at full strength. What the heck???
