Hello i see this in a lot of BGs, and usually at Alliance side (occurs in each 3rd) - only happened once at Horde side (at the first days of the server) in my experience
Any ways to prevent this or is the server doing it on purpose, because Alliance might got more players and overflood the data?
Sometimes i am queued for a BG for 5-10 minutes and then still dont join at the start of a new BG, often after they already mounted or even later
