I think it would be very helpful if you were to add some additional information to the ranked search screen. I would like to be able to see the civilisations of the people you are queuing with as well as to be able to chat with those people to discuss civ picks, strategy etc. It would also be handy to know how many people are queuing at any given time. I’ve included a basic mock-up of what this setup might look like:
It would also be nice to have the more options with regards to ELO ranges but I can understand why you might not want to fragment search too much given the relatively low player counts at times.
