I do not consider it a waste of my time. I consider playing maps that are not my preference to be a fair system of getting more people to play the maps they want more of the time, which is a good thing.
I think it’s reasonable on a auto matchmaking system.
I believe that the historical way to play was via ranked lobbies and not auto matchmaking. I have no issue with their being ranked lobbies where you can pick your map 100% of the time.
I made my own thread with more of my thoughts, rather than hijack this thread anymore.
