It's very annoying that Tarth and Wildlands borders look the same.  Pariden and Resoln looks the same.  Umber and Kraxis looks the same.  Capitar and Magnar looks the same.  Not to mention if you want to make a custom faction... then they will also look the same.  How tough is it to make two color borders like Civ V city-states or something?

And don't get me started on the empire tree and event tree.  We're only a week away from release!  I know.  I know.  You're focused on the game mechanics and balance and 75% of the world doesn't care about UI.  Well if you please the other 25% then you'll please EVERYBODY!  Ready, set, go.
