this is a myth - did it last reset with orb on tank and it was perfeckly viable - with him leading the group in patern it was quite easy boss if people know what they are doin - seems to me as l2p issues becasue Cordana is nothing but a beautiful retard check fight.
seems to me more like you dont understand mechanics in there and they decided that it will be faster finding competent tank then wipe with you in there
