Hey, so, I have been here for almost a month and just posted stuff today, and this is my first topic I created.
Anyway, would you have wished someone in Awakening had different reclassing options than what they have already? It could be for making them better ingame (i.e. giving Virion a class that can get him offensive skills without making him be stuck with the Astra bow, Vengeance axe, etc.), or maybe you just don't like their classes.
For example, I would give Tiki the Pegasus Knight and Dark Mage lines. Tiki having the same classes as Nowi is pretty lazy, like if Tiki was going to be unplayable at one point but was made playable at the last minute, and just gave her Nowi's classes because why not. The Peg/Dark Mage are basically counterparts to those classes, so they would be different from Nowi (slightly, they would both share Dark Knight). As for who could be better with a different class, I haven't thought of anything besides Virion being a Swordmaster for Astra.
For a completely random reason Chrom should be a Theif so then he can always wield Falchion. I don't know.
