The new feature that allows you to retrain skills was a suggestion from players and is there to help you all. However, be EXTREMELY mindful of the skills you lower, as the system doesn't check if you are losing requirements for feats you have. If I find people getting rid of skills they shouldn't be losing due to feats, or losing Linguistics after getting a bunch of points in languages, I'll not only delete your character, possibly ban you, but will also remove this feature altogether.
