Game Setup: Faction randomization - Unique option

In Endless Legend there is the option to have no duplicate Factions in the game, even if you set all Players to random. I really loved this feature, because you could randomize the game setup and still ensure that you do not encounter the same empire more than once. In my opinion, it just does not feel right to deal with three Horatio empires while other races are left out. Hence I would suggest to implement it in ES2, too.

Maybe it s a bit too less to only mention this one option for an idea. Feel free to add suggestions depending Game Setup, if you see fit. :)
