Am I missing something on these new races? If you actually try to build the Elarians, they cost 16 points. The standard race doesn't seem to have any negative traits to balance them out.
The Trilarians on the other hand seem to leave 4 points in creation. Transdimensional and aquatic only cost a total of 6 points. I noticed there are a lot of races that don't seem to balance out but the Trilarians are the only ones I found who are under balanced. You could make a custom trilarian race and take 4 extra points in freebies.
