Everybody who used this exploit should delete all the things they gained from it. Also I cannot understand people who are exploiting this exploit. They should know what happend with the karma exploit. Using it once, ok, if you delete what you gained from it. But using it over and over again, is not okay in my eyes.
On the other side, ArenaNet should also fix the event where you have to protect Magg, and you can get him out of aggro range as elementarist and the skill Gylph of Renewal.
