So, there is a lot of rabble rabble about ratlings being boss snipers and non-abhuman friendly players not wanting to have to be a ratling to be a sniper. While the easy solution to this is play a ratling and call it a human, people have brought up good points that "house rule it" is not the point of a beta test. Someone else also made the point of "not all ratlings would be snipers."
In Deathwatch, everyone has a choice of race in the form of chapter. I feel the same system could work here. Make abhumans a template applied to the characters rather than a class choice. Much like some chapters have restricted specializations, so could the abhumans. I get this a bit of a major change but I thick this is a working compromise.
