That’s cool and all but you know how I know they aren’t doing this and you are just making stuff up?
There’s no # for the battleground pop up and there hasn’t been for a long time, it was nerfed in 2020 to stop alliance premades queueing for alterac valley
There is no way to know which battle you are entering and you also cannot see the enemy team until enough of your team joins so you can’t even dodge other premades by sending in 1 guy
