This has happened 4-5 times now. I join and alliance already has 1000-1200 resources and Horde is just starting to filter in. It’s as if the entire team left. Had it only happened once I’d assume it was a premade leaving, but it’s consistently happening now.
I have also joined and there are only 3-4 other players and the match starts. That said, this is happening on other maps as well. More than 1/2 the bgs are starting with not enough players.
