I think that Hungry Hills should be added back because of the new voting system, I mean, it could work. Nowadays you have 5 randomly selected maps, and if Hungry Hills is played, then it can't be played again for another few games on that server. On top of that, you can see the map being played next to the server on the server list, so if it's Hungry Hills, you could just not join.
Of course, this might be a drag for non-donors that don't like Hungry Hills, because they would have to leave and then find a restarting server all over again. But to debunk, there's now 76 servers, and getting in a game has never been easier.
Crossing my fingers for Hungry Hills.
