Dungeons: Find A Partner should only match players with the same in game language setting
Since dungeons is all about communicating with your dungeon partner, wouldn't it make sense that you can actually communicate with them?
I've been getting a few matches with players that don't have the same language settings, it's fine if it's obvious who is going left and who is going right, also if the other player is experience enough to take out the obvious node, but there are occasions where players like particular nodes to be left more than others.
Auto translating quick chat short cuts is also an option, but I think the simpler solution would be filtering based on in-game language settings.
