Man i miss all the good stuff…what exactly is this abuse though? i dont go to reddit..
Basically people from all 3 servers gather in OB usually with Guardians,Elementalists and Necros, take a bunch of AoE and Retaliation then run into the aoe circle throwing all you got into it to tag other before you die, then use waypoint and jump down again. There are stories that a lot of exotics,mats and precursor were dropped. The farm was used mostly to advance the WvW rank where you need to kill 250.000 players but people slowly turned it into a loot fest. It was short tho because you could only farm 20-30 minutes before Deminished Return hits in and you would get no more loot.
