Today I was playing Dream of Five (on a side note, are they still working on the FEXNA port?) and I got Lia promoted to Valkyrie and the Mage Knight guy (Stolypin, I think). So I thought: why can't we have mounted unprompted mages? because they would be OP as fuck
You could have Heralds (mounted Anima mages), Prophets/Apostles (mounted Monks) and (something?) (mounted Shamans).
Since I had nothing better to do, I thought of some other (not) interesting ideas:
Legates (Sword/Lance), Guardsmen (Lances/Axes), something (Axes/Swords) in place of the usual Armor Knights.
They may or may not promote to Generals, but I can't think of other names for them.
Next up are Pegasus Hunters and Falcon Hunters, Bow-wielding Pegasus Knights. With this, we have officially decided how bad a class can get (just kidding, Falcon Knights are my second favorite class after Swordmasters).
So, I'm into Greek history and mythology and stuff, so I believe a class such as Hoplites would be a cool idea: they are Halberdiers, minus the Crit bonus, plus Swords, with less Strength and Skill and more Speed and Defence.
By the way, I'm posting this in Concepts because first, it's a concept, and second, someone may actually find this interesting and do it in a hack.
