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. :-/
Actually, this is not the worst trade-off in the world, even on the roleplaying sense. I can always think of humans as those generic city guards wielding polearms. And gameplay-wise pikes are one of the best two-handed weapons in the game, Larian gave them the best weapon actions for Martial Classes.
