So, the name of the thread is almost self explicatory. With the huge amount of mastery and dodge/parry being reforjable, it gives 20+ str than the rep one and the 359 rings?
So what do you think, is it worth later on?
My advice - do the math using the latest stat weights; generally mastery on a tanking item compared to haste/crit on a DPS item, in combination with additional strength, will prove to be an upgrade, but you should always check on a case by case basis.
