Perhaps the least satisfying part of this is how unplanned everything feels. Mustang's and Armstrong's plans, if concocted together or separate, they are both pretty bad and don't really address the real danger. Hohenheim's plan doesn't sound very good either, Al's quite bad as well. I mean, it's not even stupidity at work, it's just that... who ever thought those plans make any sense at all? It's also strange to accuse FMA of „lack of realism”, but... :D
