Firstly, I apologize if this is the wrong place to report this. Also, as the title says, major spoilers. You've been warned.

I came across a very overpowered glitch regarding the lone wolf perk. Once the respec demon is available in the homestead, if you use him to reset everything, you don't have to re-pick lone wolf, allowing you to get companions/henchmen while retaining the redistributable ability points you accumulated with lone wolf, thus having double abilities as well as a large party.
