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. Lets us play Githyanki as racist as they trully are!
