I am for the increase to 32. I agree with the basic premise that Creamsteak has put forth, also, it allows a character to have 2 18s if they want, at the sacrifice of 8 in every other ability of course, but it is there.
2 points doesn't seem like a lot, but, having made many a character on Never winter nights, which uses a buy system of 30, I can see where it opens many new doors.
