Truthfully I would say you may want to retire him. Not trying to be mean, but you will be behind other players down the road(most likely) Here is what I think you might have done wrong, you have spread your skill points around to much, by lvl 4 you should have been able to softcap(48) strength. From the start it should be strength/carrying until you can soft cap strength and then 2nd, and 3rd cap strenght.
Just my thoughts I could be totally wrong.
