Wit and ini is fine the way it is. Go buff Con and Mem because those 2 are the weakest stat atm in any good min-max build. Con is a joke stat and Mem is a waste of point on non-mage because most skills have been nerfed to barely deal any more damage than normal attacking. Only mages really care about Mem now because they have to be able to use all the good spells of every school to be useful if they don't want to be a summoning tool.
