Mastery is great but I have to agree. 58 parry, 60 stam and 188 dodge is much better than 193 mastery. Even without the stam difference id say 58 parry + 188 dodge is pretty close to 193 mastery if not better.
While stam is no longer the way to go don't think it is useless. Alot of harder bosses will wreck a tank and stamina still plays an important role in tanking, don't prioritize it but don't dismiss it either.
He who is afraid to lose will never win.
Only when the power of love overcomes the worlds love of power, will mankind know peace.
