Tried to do some research, but dunno if this has been mentioned yet:
During character creation it's possible to redistribute ability points in such a way you technically no longer have the required ability score for your starting skills.
For example: As battle mage you could redistribute ability points from fire elementalist to earth elementalist. But when you do this you technically no longer have the required ability score for Burning Touch. The skill is still usable though.
It would be nice to be able to choose the starting skills (from a fixed set). That way you could choose new skills, when you change abilities. Maybe even reset the skills, when abilities have been changed.
Also the bonus ability points and stats for the "All Skilled Up" and "Bigger and Better" talents are not available during character creation. They can be spend only after the game has started. It's not that big of a problem though.
