Cause you're doing it all wrong. I got with a 10 man raid group and did CTF like 10 times in an hour.
It's important that you don't have 8 ppl or 9 ppl in your RAID.
GET 10.
Also if anyone disconnects or dies at any point while you're waiting everyone leave the queue and someone have the group entered into the queue again once all your party members are alive and people who were disconnected are back online.
ALSO make sure NO ONE goes AFK because when the battlegrounds is ready for you to enter you must be ready to click enter immediately.
I did battlegrounds over and over tonight and it was a BLAST. Meanwhile I saw friends trying to get in by themselves and getting the shaft.
I got home from work at 11:15. By 2am I had around 200 HK's, 1/3 of the way to Friendly with the warsong dudes, and had done 6 CTF in warsong gulch. BG's are hella fun. The trick is definitely getting your 10man in.
