I have played this 3 times without imperial win. Davith in one and Shyla in another had control of the whole map due to their mobility. (And the third one despite spending 3 influence worth of agendas.)

In addition, the Lobot's Favor reward is very overpowered. When played in some other campaign (such as Jabba's Realm) I would change the activation cost of Lobot's Favor from Deplete to Remove from the game.
