Huh, you're right, it doesn't change the Attribute spread at all. So with the Shapehifter Abilities listed for the Fox are: "–1 Reach*, Enhanced Senses (Hearing, low light vision, smell, taste)" (RC p.86) he wouldn't gain anything from the Not Always Quite Human (RC p.87) except the loss of two of his Enhanced Senses (if you have a strictly by the book GM) or just gain nothing... Seriously, just ask your GM to be an Elf for free, you gain nothing.
