Well now it wouldent be a good idea considering you already trained his stats...
You should create a pure ranger, with no combat (att,strength,def) stats...
Pure mage : only train mage at first, then when you lvl 40cb +(you can get def up to 20 or more)
Pure Ranger: only train range then get def and other skills up after you hit 40cb or w/e..
But the stats you got now youd be waisting your time on a pure.
