So, considering the following solutions:
- To hell with the rules - if I want to build an 8-point wizard/fighter class, I can make it work as a human with a lower max level and justify it as 'jack of trades, master of none.'
- Another arcane race - probably the Zaharans. Honestly they match the flavor I'm looking for for elves in the new setting anyway, where the elven empires of the south have fallen to darkness from within in the Melnibonean style. Ruinguard fits the fighty-mage archetype well (though it could stand some better casting and fewer prime reqs), and a Zaharan nightblade equivalent would be both thematic and easy to cook up. About the only thing I don't like about the Zaharans is the name. I need to spend some time reskinning things and coming up with better names, I guess. I suppose High Elves (arcane, fallen) and Fey Elves (nature-based divine casting) will do as working names for now. Then it's just a question of unifying a few racial traits and tweaking a few new classes (ruinguard/spellsword, nightblade, elven ranger as explorer + fey divine, and then a wood elf shaman+arcane sage/farseer class).
