Gj on solo-tanking and pushing that amount of dps. Just makes you wonder if DT is balanced at all.. oh no, shouldn't have started that diskussion.
Ghola should know what DT is capable off. Both him and Thaan have topped (or being near top) in damage done/taken and healing done/taken at the same time in some T4 encounters.
I've personally seen Azi (Izkraticus) do 5-6k single target in pyjamas set - so ofc. 2.2K and tanking will be possible.
