Your thinking way to much along the lines of what you are used to as mage/wizard in other games.
Int, Str, Dex all very usefull still so pointless when regarding warrior/hunter/wizard classes.
Its not the standard
Str = warriors
Dex = Hunter
Int = Wizard
Pay good attention to the mouse-over info you get on Conditional body/Heightened reflexes/Indomitable will
If conditional body or indomitable will are lacking your mincemeat.
Small tip though do not use charms giving those stats just use Str, Dex, Int charms to increase what you need as they will give you more bang for your buck(/charm space).
