I play affliction and I have 3 pieces of t9.5 and one piece of t9. I recently got a token for t10.5 and was wondering when I should break my t9 4 set since the 4 set for afflic is very powerful. I have 9.5 helm, legs, gloves, and 9.0 shoulders. My chest is merlin's robes. WHat piece should I buy? or should I just buy and hold onto it for the 2 set?
