More plot convenience, eh?
The best Rebel squadron, whose last mission was devoted to the destruction of the Death Star, is actually nowhere in sight when it has to be destroyed for the Rebels to survive?
I prefer my plot convenience to actually be caused by the needs of the plot, rather than by silly retcons based in marketing hype. Had this movie been called Red One, there wouldn't have been an issue.
I discuss to learn, not to win. Then again, learning enough tends to translate to victory in the end anyway.
