Disclaimer: Not making fun of EU, just an observation.
It seems a lot of EU DT's haven't really caught onto the obscenity that is tali tanking/desecration tanking. 1700 is nothing too crazy when I managed to get this on my very first parse and I was doing an awful job of debuffing (two unhallowed blights in total!). This was done in Khemi on a single strawman so it's a 3 minute fight.

Pots were running - though not my full typical T4 setup which runs the wisdom/crit damage pots. Spec was just my basic Zodiac tanking build which I can solo Zodiac on. Gear was full Indom except fearless Chest + BD helm, band of the immortals, band of celestial bureaucracy, watcher of the den, cloak of wakening nights. I have a second wisdom ring which would have done more DPS but I rarely run it due to lower and lower mitigation problems you run into. Best setup IMO is fearless majors, courageous shoulders/wrist, everything else indom so you can max out your wisdom accessories.
Spec is this:
