I like the idea of a mounted archer, I tried it with a gnome druid on a llama. I could have build him a ranger but I wanted to take Eldrich Archer later on. He was pretty effective, with the llama speed he kept out of range and could damage with the bow or spells. Sadly that campaign didn’t last long, so my experience is from the first 3 or 4 levels.

A similar idea I have now that Guns & Gears gave us the gunslinger is making a dragoon inspired character. No, not the Final Fantasy class, the historical mounted infantry unit. I would probably make him a spellslinger and maybe a beast gunner since I like casters.
