A free feat for humans would really be strong, maybe too strong. And as the game is already quite easy, a free feat for any race at level 1 would be surely a problematic feature.
For my taste Human Militia is a very welcomed and strong feature, it especially makes Gale and Wyll so much better. What is debatable is that half elves (my preferred race, but because of visuals actually) also get it although they are already very strong from racial bonuses.
