1 hour and 29 minutes in 29's back during BC.
I'll not forget that one as that was the first time I sent a GM ticket in.
Horde FC did the tower climb exploit. The GM answered really quick and ported the offender to mid-field. Stayed around to monitor the rest of the BG and when the guy did it again, he got booted and our flag returned to our base.
Thank goodness was beer and friends on a LAN.
