Game Mechanics: City of Mist: Abnormal Black Reaver trains

[Bones]

The roamers on the second floor walking across the ramparts will chain aggro on the mobs on the top room in the temple if you pull at the wrong moment. It happens quite frequently. It trains the moat group because the mobs on 2nd floor that you chain aggro'd had to run all the way around the zone and out through the black reavers at moat.

I don't think this is a mechanical bug of any sort since its been going on since kunark launch you just need to be careful with your timing pulling that top room of temple or don't pull it at all.

Edit : this has been used as a form of griefing moat groups for years
