Headscratchers / Fire Emblem: Shadow Dragon & the Blade of Light

• Why do some of the reclass sets in Shadow Dragon and New Mystery of the Emblem allow units to become the promoted form of a class whose unpromoted form they couldn't actually use? For instance, characters in both games with the Male A reclass set can become Dracoknights, but not Pegasus Knights, and characters in New Mystery with the Female reclass set can become Generals, but not Knights. It's understandable why they gave females access to the General class (because Sheema was a General in the original and they didn't want to change her class), but why couldn't women become Knights beforehand, and why were men given the Dracoknight class at all?
  • Answer: Having characters from the original games that are classes that would be otherwise "one gender only". plus laziness in not making different gendered version of the earlier class. As you mentioned, Sheema is a General, the promotion of the male only knight. Thus, girls can be generals, but not knights. This next one applies more to Shadow Dragon than New Mystery, but girls could only be Paladins because Midia was a Paladin. There is no Girl Cavalier options until New Mystery. Male Dragon Knights? Micalis is a male (sure, he is enemy only in Shadow Dragon, but they have to code that male Dragon Knight class for him, so they might as well put it to use!)
• Why doesn't Marth instead use the staff to resurrect his father or his mother? It's not like Marth cares about succession at the moment and reviving his father to rule would allow him some more freedom for the next few years until he dies again.
