The population isnt to big u wont see many queues to get into the game but there is a decent amount of people. Sometimes PF is packed and others theres just a couple. And yes we are on mumble hanging out. Sometimes we talk so much we miss text but we do our best to have a friendly atmosphere through voip as well as text. And yes its a big decision that cost money so i would recommend creating a player and trying it out for any server u may go. I hope u make the decision that works best for u as well
