So I was in Kessex Hills just doing the normal DE's, boss fights, collecting mats, etc when I came across a DE where you and to prevent Centaurs from rebuilding a bridge. I did the DE and noticed that no one moved but just continued to launch AoEs all over the place. I thought they were lagging (or I was) so I went off to explore around the area and see what else was out there.
There was another DE that kicked off near by so I went and did it and noticed a that within a few minutes the same 'repel the centaurs' started up again. The same group of people were standing in the same spots casting the same AoEs. I went and explored the rest of the map and on my way out, wouldn't you know it, the same people...standing in the same spots...casting the same AoEs.
Are these just account sellers or is this how people 'power level' in this game?
