Luckily ...
It seems like character creator lists all your proficiencies, no matter if they are duplicate.
Ands it seems to be written in order class > race

So ... in version we have seen in PFH.
All races got fluid +2 and +1 ...
And humans got polearms proficiency (spears, spikes, halbeards, glaives) and light armor proficiency.

Honestly, it doesnt seem like very good deal to me. :-/

I still dont understand why cant we change Race for our hirelings. frown
Lets us play Githyanki as racist as they trully are! frown
