Humans??? Hm...
Maybe instead of a lot of racial skills, just let humans transcend with out a shard...

(Not gonna happen....but fun to dream

)
Here's an idea - stolen from Vampire: the Masquerade (among other games)
Humans can choose from a list of pros and cons during creation that not only help define their character, but allow for stat modifications within realistic boundaries.
Example -
Con -
Blind - 2 point flaw - can't see, can't have 'cure blind' cast on you.
One-eyed - 1 point flaw - limits vision for skills such as survey and ranged attacks
Deaf - 2 point flaw - can't hear anything, including says. Can hear tells and global channels that aren't vocal (Can't hear shout but can here chat).
Pro -
Heightened senses - 2 point pro - (available only to those with the flaw Blind or Deaf) - Due to the lack of one sense, the others are heightened to compensate. Blind individuals with this pro gain listen at perfect innately while those who are deaf get innate detect hidden and/or search.
Specialize - 1 point pro - you specialize in wielding one type of weapon, such as swords versus daggers or spears. Gives bonus to hit with weapons of that type, perhaps small damage bonus due to increased accuracy at hitting vital spots.
Etc.
Some pros and cons could be taken more than once, for ex. taking blind con and then specializing in swords and daggers.
Wouldn't be available for youkai and hanyou because they can regenerate, attach body parts from other creatures, etc.
