just some type of conection to the coming burning legion xpac with garrash already cutting deals with demons and maybe completely going opposite of his father and reverting what his father died for . freeing the orcs of demon blood.. but he mistakenly is doing it for the better of the horde. then when he is defeated or killed someone can remind him how unproud his father is and this is not what dad wanted.
the way they went was pretty predictable , imo,.. would him using demon blood steroids been more of a shocker and slap in the face to the orcs and his father? I would've preferred a burning legion conection.

I didn't find the right solution from the Internet.
