As for 'multitalented', I think that it would be redundant in this game.
The only reason I consider it is because my character will be light on rogue talents as an Eldritch Scoundrel, and a few more just to cover utilities wouldn't hurt. Elves get 1/6th an Arcana as a FCB, and humans 1/6th of a Talent, so half-elves could get both. Elves could get a +1 fighter FCB to CMD to resist disarm and sunder attempts, but I don't know if the feat buy-in would be helpful in surviving the GM's challenges.
That's already possible in the race builder:Start with human (9)
Switch stats from human to flexible (+2), That covers 2/6 stats.
Now take Advanced for the other 4 (4*4=+16)
...so an Azlanti human would be 27 RP. An Azlantified halfelf would be 28 RP.
Thank you, that's perfect!
