I liked the emperor, it was an obvious pretend-do-gooder manipulator from start to finish, what I don't agree on his writing it's the end where he switches teams.

Would've been better if he just teleported away from the city, and in the epilogue , a scene of 2-3 seconds of him on a building watching over us at the docks. Which would've let room for interpretation and possible future DLC to expand more on this fantastic character since I feel we didn't get enough of him and his ending didn't make sense at all.
