weapon types: Bows, Lances
This sorta reminds me of my idea to split Nomad Troopers and Horsemen/Rangers by giving the latter lances instead of swords, and a slightly heavier-weight stat balance.
I had an idea for a Samurai class, although this would require an in-world explanation in order to be present.

They're basically heavyweight swordfighters with an emphasis on Skill and Defense. In a setup that has Strength and Magic present simultaneously, their Magic would be less terrible than other physical units', as well. As they wear heavier armor, Samurai aren't as fast as other sword users, and their Luck isn't very good, either. Resistance is kinda above average, I guess, but not really that noticeably so; at least not until later on. Constitution is 9, and movement is the standard for non-mounted first-tier units in their setting. They also have the benefit of being less inhibited by terrain than Knights, suffering from few abnormal terrain movement penalties.
Equip: Swords, Bows

Shogun are... well, basically just stronger Samurai who can now use bows in addition to swords. Their caps are adjusted to allow for high defense and maximum skill, but their speed and strength potentials are only mediocre. They gain one point of movement and 2-3 constitution upon promotion, though, so there's that.
Just an idea I had that I thought I'd jot down here.
I've also had ideas for shield-wielding mages, a Staff -> Dark/Staff class, (these two could be merged,) and maybe some form of flying unit that specializes in something other than lances or axes. The above is the idea that I thought I had fleshed out the most, so...
