I host many games with Siege of Feldmere map-very good for 4 vs 4 team games.
https://www.warlight.net/MultiPlayer?TemplateID=837713There are some filters, but they're not very strict.
Only a very few join and for a game of 15 turns or so happening in 30 mins or so we need to wait for 30 mins. And then there are some players who make it to end in vote, as they leave after joining the game or surrender soon or pick wrongly.
