Orrian set
power/prec/tough for some extra survivabillity. I just like it on my thief knight armor ftw!
I had the same issue yesterday and went for pow/prec/crit, because regardless of packing toughness or not Thief is always very squishy.
I decided to go with pow/prec/crit because full dps is often in demand, and I’ll make up for the loss of toughness on armor by making jewelry that gives vit/toughness and pow/prec/crit.
This way I can swap on the fly to full dps and slightly more durable/less dmg specs depending on the situation.
