How is this different from matching?
LFG is about the next hour: you need three more players for the game that is open on your screen. Matching is about finding the people you will keep playing with. Different problems, different screens — most players end up using both.
Do I have to use a microphone?
No. A party owner can say a microphone is expected and that shows on the party card, but it is a statement of intent rather than something the app enforces. If someone joins a mic-expected party and stays silent, the owner can remove them.
What stops someone toxic from joining?
Two things. Requests come to the owner first, with the requester's rating and badges attached, so a pattern of bad behaviour is visible before you accept. And a decline can be made permanent, so the same person cannot keep knocking.
What happens to the party when I leave?
If you were the owner, ownership moves to whoever has been in the party longest, so the squad is not left without anyone who can accept requests. If nobody is left, the party closes.
Is there a way to be told when a squad forms?
Yes. Instead of sitting in an empty party you can join the queue for a game and get a notification when a squad fills up.
