I hate to have to breach this subject, but the recent subrace ability score is super awesome, thank you for that change so much.
There is one tiny matter that should probably be brought up though. Subraces that lose -2 to hard STR, DEX or INT (and there are many such subraces) are going to have feats on their character sheet that they should not have qualified for and opposedly they might very well have not qualified for feats as they had leveled up that they should have done. I really think its a very good idea to do an auto relevel script for the subraces affected by this change. Otherwise there is quite big balance difference subraces created prior to the ability score change and those that were created post change. Thought I should bring this up. Not to mention characters that would gain or lose skill points from INT changes (that are not retroactive btw) so it would correct skill point totals too.
