rogues or any stealther... much easier on a gobo engineer rogue like my self. zone in heroic UB, go right, make your way up and past the first boss, proceed to the ledge thats over the first chest( when u zone in its to the left, gaurded by 3 mobs) u should be standing directly over the chest, on a ledge thats just out of throwing range. thats why the gobo rocket comes in handy, if your a druid or mage, simply hit the mobs below with a spell, nothing will agro you here, wait for the mobs you shot to coming chasing after u, takes them 1 minute 40 seconds to get to you, mage druid need to jump on edge of ledge to lose agro as the mobs cross the bridge or hop in water away from da fish or if your a rogue just vanish hop down and loot chesti made roughly around 2.5k in one week doing this... when u get your chest, zone out and zone back in, there will be another one... no need to reset just dont kill any bosses or do it while in a group. hope this helps and i dont think i have seen this anywhere else. good luck
