Just wanted to give an update.
He is enjoying the hunter, but prefers playing with a greatsword. Instead of leveling with him, I am babysitting him with my Scrapper for the medic and bulwark gyro. I am underpowering myself by using a flamethrower so things doesn't die instantly. If we do run into group event we can duo it at least if I am on my scrapper.
We spent a few hours today just taming pets for him. He loved it.
