Disagree. If NO_UNIT or NO_UNITCLASS flavoring (either way it means -1) is found as the only flavoring that's been added by any GP pts, it should randomize evenly between all GP types, sure. There may not be a protection in place for that at the moment. However, it's very unlikely to happen. Otherwise + GP pts unflavored should just be a magnification effect and make it faster to get a GP born but not have any other influence at all on the type likelihood and allow all other sources of flavoring to determine it as if it had just lowered the threshold to get a GP. I don't want 'colorless' GP pts to add chances for GP types that were otherwise unsupported in the birthing process. AKA, if I didn't add any Artist points, I'd better not have a chance to get an artist just because I had some 'colorless' GP pts added during the process. Reading onward, I highly prefer option 2. In your example of adding the priest pts at the last minute, yes only a priest should then be possible. As for Sources of 'colorless' GP, there aren't any buildings that do it right now but there are specialists, the Noble at least being one, maybe the only one.
