Reincarnate & human bonus feat

[Kask]

If the feat comes from longer term knowledge, elves should get 2 bonus feats.

Nope. Living longer is not equal to learning more. Otherwise you wouldn't need to study. Just sit there and gain knowledge.

To answer one of my own questions, I realized:

elves receive the Martial Weapon Proficiency feats for the longsword, rapier, longbow (including composite longbow), and shortbow (including composite shortbow) as bonus feats.

A reincarnated elf actually retains three racial bonus feats! So Reincarnate doesn't exclusively favor humans. It's still not fair by any stretch, but at least it is not adding a big benefit exclusively to what is already the most popular racial pick.
