As a new player that wants to play only in private matches with friends, i find that maps requring certain levels to play is an incredibly frustrating mechanic. The idea of new features opening up with higher levels is not bad, but it really sucks the fun out of the game when you cant play on the map that you want. Also i didnt quite figure out how to see at what level a map becomes avalaible, i would appreciate it if someone explained which level is this map: https://www.warzone.com/Map/19019-Metreoque-LondonMoskva

When creating a game, maps you have not unlocked yet are hidden by default.

It would be useful to know at which level a map does unlock at on the map page. You may need to create a feature request for this - https://www.warzone.com/Forum/f12-Feature-Requests
