At the moment the Skill Master leadership bonus is never used because it is a party perk that grants SP. I propose to change it to grant cooldown reduction instead. (or something else to better reflect the idea of Skill Master). Imo every other leadership perk has an use except this one
Thank you for your suggestion, we've decided to accept it. It will be added to our list of upcoming changes, and our game design team will consider what new bonus that skill should provide moving forward.
