The new AV exploit
Be aware battlegrounders. There is a new bug in AV that allows flags to be capped through walls and from 10 to 40 yards away. Possibly even farther if you are a hunter and use Eagle Eye. No word on if the Spyglass affects this. This is primarily a problem in Alterac Valley, but also in Arathi Basin. At the Blacksmith location in Arathi people have been hiding in the building and capping from inside.
People are capping through hills and from behind trees. Hunters are reporting standing at the flag, with their pets on aggressive, and the pets do not aggro on the cappers. That’s how far away they are.
So widen your defensive patrols and watch for the golden swirlies to appear on your flag. Someone, somewhere is trying to cap it.
Update: Patch 2.0.4 fixed the bug.
