At the moment i find that 2 types of dpseccs work well for me, With t4 mainparts, tiger and strengt,crit and hit rings nec ect, one is pure desecration specc without any Points in tali, meaning its a sword and Shield dps specc and not realy a tali specc, still need goad and cunning and a few other in general, id say 16 Points.No prob tanking zodiak With it.
The other is pure tali specc, all the way up, no dooming presence. With goad and cunning. few Points in ironskin and/or impd def stance. Still abouth 16 Points in general. This Works for me, but might be horrible for others, its simply a try and and learn road
I Guess its the reason im so fond of the dt class
