Shifters would be a great choice of class 4 duelling in Gs except that generally shifted creatures have terrible AC's, even worse AB's and awful DC's for the creature abilites. Is there no way they can be incresed? Even if you have +6 AB/AC from str + dex in items when shifted, thats still really poor.
However, if you add all of the armor/dodge/shield/natural/deflection AC bonuses I think the AC would become too much, so I had an idea - to add the dodge & natural AC bonuses, the weapon attack bonus (and weapon damage to unarmed forms) and have the creature ability DC's at 10 +1 per shifter level+wisdom modifier (to make them usable).
What do you all think about this?
