There is a suggestion that I brought up on the CC boards, just need to get it to the Devs plate. The suggestion was that 3 different version of the racial ability was handed out. I suggested low at 2, middle at 8 and high at 15. Its not nearly as tedious as handing out a new one every level but allows for some form of progression.
Potential issue was how many more items would have to exist in the pallette. It would triple the racial tools in number.
