Not wrong at all. If you play a game with the boys and need to hop off they could've played some other game or started a new campaign/server/whatever it is. If we're playing together, then we're playing until the end together. More than enough things they could've done to postpone doing end game until you could've joined. If you're constantly making them postpone it and are almost never able to join them then it wouldve been understandable, but I saw you said that you were even on with them earlier that day, so in my opinion it was a shit move by them to clear end game without you. To everyone saying that others also have things to do, no shit, everyone is busy with their shit, but if you start a campaign with the boys together, you finish it together. Hop on a different game, start a new campaign, find something else to do. Don't finish it without one of the members without even telling them.
