If I didnt buy DLC, I dont know about new civs, then I match with players with new civs, like japanese, I do not have the knowledge of his civ but he knows my civ. This put those who didnt pay for new dlcs and disadvantage. this is still pay to have advantage in ranked.
if i dont buy dlc i am limited to older civs which is enough for me. but since I still get matched with people using new civs, it still forces me to learn all those new civs that i dont own and i did not pay for. Ranked games should match players picking new civs only to those who own dlc.
