So I was rethinking the classes and stuff. I like the weapon triangles in Fire Emblem Fates. I don't much like how magic is handled, though. You're throwing the book at your enemies (literally!) while using combat-hardened staves to...heal. I suggest swapping the roles of tomes and staves. Complex magic tasks, like warping, fortifying, and healing, should be adequately written in tomes, while cheap destruction should be the purview of staves. With that, I present to you the weapon triangle:
* Swords & staves beat
* Heavy (axes/clubs) & bows beat
* Polearms (spears, naginata) & hidden (knives, shuriken, kunai) beat
* Swords & staves

Now for the base classes:
* Lord: swords, access to McGuffin
* Mage: staves (ranged magic attack)
* Sage: tomes (support magic)
* Archer: bows
* Rogue: hidden
* Myrmidon: swords
* Fighter: heavy
* Lancer: polearms

Note that mounts are handled separately. Fliers generally cannot bear much weight, so knights and paladins are relegated to horses if they want a mount. Available mounts include horses, wyverns, dragons, phoenixes, griffons, pegasi, unicorns, and winged unicorns.

Promoted classes:
* Warrior: swords, bows (promoted from Myrmidon, Archer)
* Wizard: staves, tomes (promoted from Mage, Sage)
* Assassin: hidden, swords (promoted from Rogue, Myrmidon)
* Ranger: hidden, bows (promoted from Rogue, Archer)
* Paladin: heavy, polearms (promoted from Fighter, Lancer)
* Knight: swords, polearms (promoted from Myrmidon, Lancer)
