I see people think very highly of admirals. Sure, they are your favourites for you (those who like them), but at the end of the day you have to remember this is Luffy's story and his crew's story. The admirals are basically the villains of the story, not the protagonists. Sooner or later they will be nothing more than a memory to the crew. An obstacle to surpass and defeat, that's all they are! Fodder basically, just longer lasting fodder than the usual fodder.
Never forget that.
