Is it me, or is Combat Expertise too watered down? Why is it now based on intelligence? Most fighters do not have a high intelligence, so that now limits their ability to increase AC?
I never saw a problem with allowing a character, weather it be a fighter type or not, to taking up to a -5 penalty on their attacks to boost their AC by +5.
To me this is too drastic of a change.
Other than that, GREAT WORK!! Thanks Paizo!
