I’ve posted some odd things today, so to make up for it here’s a tiny bit of FE13 meta to contemplate.
Could reclassing be considered canonical? In its 11-12 incarnation reclassing is comparable to the FE10 support system in that it sacrifices characterization in the name of gameplay. As minimalistic as most of the characterization in the Archanea games is, I think most would agree that, say, Bishop!Jagen, Myrmidon!Lena, or Dark Mage!Ogma are not very plausible given what we know about them.
Reclassing in FE13, however, is character-specific and sometimes even draws from information we get in supports. As an example, Cherche mentions in one of her supports (with Vaike I think?) that she met her wyvern while training to be a healer. Her other two class sets are cleric and troubadour. Not every character’s class set fits so well – Cavalier!Ricken? Dark Mage!Libra? – but I wonder if it’s something we ought to take into account when discussing at least some of the characters. Conversely, it might also come up in discussions of classes; were someone to talk at length about the representation of dark magic in Ylisse, would they have to consider Libra, Cordelia, and others who can reclass to dark mage/sorcerer? I think we can safely ignore the I-can-do-everything-because-I’m-a-player-insert Avatar as well as the children characters and their varying inheritances.
