The idea about guild promotions is that you get to buy more valuable traits the higher your guild standing is.
As to "gotten", I think it is the Ameriacan version of the past participle whereas the British would be "got". I am not quite sure, and generally we do not tend to criticize each other's grammar. But now that you ask... Bungleau has been so kind to lecture me a bit in English grammar in private messages though. But that was only after I corrected his Danish on the forum.
