Lol, Yea I would think that not promoting him would have a Lot to do with him being weak. Yes you just need to take a bit of a break from questing and invest some time in your companions and train them up. Trust me, it will really pay off for you.
i envy you people who have him. Kobe isnt very good
Yes he is. Despite his very low health, he strikes a LOT, especially against Swashbuckler, Buccaneer, or Privateer enemies. He had a good clean fight in the Cavern of whispers. I forgot the pigs name, but he was a Swashbuckler. He wiped the board clean, no kidding!
