Slade speculation. Formerly a discussion on Natural attacks.

At a -5 penalty and as part of your racial features... no, no it's not unless that tail attack and/or racial package is good enough that you should've gotten LA.

A feat is a feat and if you only took it for flavor, it's not a feat, it's a bit of roleplaying fluff.

So, thusly, there must be some mechanical effect.

Maybe I've been playing in a group that probably would care far too long.
