If you want to argue that the requiem arrow is an asspull, you might as well say most methods of progressing a story are. The gang could of beaten Diavolo, as he says himself that his main weakness is when his opponents are together. This is mainly because his one element of surprise puts him right up front with his enemy. Gold Experience is also shown to be very powerful on it's own, and Giorno could totally use it in a creative way to beat Diavolo. But most likely to create a more monumental ending (and maybe even to get a new strongest stand), we end up getting the requiem arrow.
