I think I want to go after two other newer classes: the 3.x/4e/PF Sorcerer, and the PF Oracle. I've always liked the idea behind the sorcerer, the natural aptitude for magic is an interesting variation... especially with the magical bloodline fluff that both Paizo and WOTC went on to implement in it. I don't yet know how I'm gonna work it, especially if I want to keep things simple, but I'm going to do a little researching, and maybe discuss it around the usual places, and see what ideas there are to see.
The Oracle I know less intimately, but it seems to me to stand as a take on the Cleric concept that is less fraught with the implicit assumptions that have so frustrated me on this blog (even if I've learned to live with them... it would still simplify my life to not have to. So I want to see where I can take that.)
