Since there is no UI suggestion section on this forum I decided to post this here.
In pubs, if you quick join a server with a game in progress or even join through the server browser but didn’t pay attention to the map in progress, then you’ll have no way of knowing which map is currently going, except maybe if you get a relevant audio cue (I’m thinking train mobbing in trainyard).
The only thing shown in the Lobby UI is the next map, which incidentally is never the one advertised as people have three choices which to vote from. It would make much more sense to show the current map in progress, so that mid-game joiners can make an informed decision on which mercs to take along.
That would be all.
