Reminds me of a ranger in a game I DM'd who had 10 Wis and 14 Int. His backstory involved him hailing from a barbarian tribe, and he decided that he would return one day in order to educate the barbarian children and teach them to be literate. But I digress.
I agree wholeheartedly that you are limiting your survivability with both realtively low Con and Dex. I'd suggest boosting one of those at the cost of Int or Cha
