[@ELGainsborough], I will admit you have my attention with this as a promising enterprise. I will not make it unclear to you that I am an optimizer by trade, but I am of the vein who do so to match a character ideal. Of characters? I am partial to druidic summoners, shamans and shapeshifters, warrior-clerics, combat psychics and expansive theurges; the latter being entered early with some finesse. When possible, I go with unusual, often beastly characters but even where inappropriate all of them have a primal theme underlying in them.

As for elven subtypes, more than anything they vary in their ability score adjustments and their culture. I cannot think of any significant changes beyond those.
