@OP: Because the only people left who have Relics and not Empyreans tend to be the biggest whiners in the game. Emps are not that hard. If Amano being second best bothers someone, they can get a Masamune and still have both weapons for whatever content we get at 99.

Getting the best in 2007 doesn't earn you a free pass for the rest of the game's life. If you want to be the best, you have to keep working to stay the best.
