Got an RNG Piece of Armor

[Backsmack]

Hello! I got an RNG piece of Conquest gear that would, unfortunately ruin my set bonus, but give me a lot of mastery and Multistrike.

I am having a hard time finding out what I want to do about this...Above in my armory you will see I have the Blue Legs for PVP, but yesterday I got Epic legs. The loss would be my four set bonus, as I already have hands for Conquest from the RNG system.

This leg here is what I received. Should I replace my current legs, the blue, with these? Sacrificing the set bonus?

I'm not really sure but I think that you should get chest/legs sets for 2 PC bonus and rest with highest mastery stats if you play Assassination. Our 4 PC bonus will be nerfed to the ground. Though I cannot be sure if it's worth losing 4 PC.

Exaclty! I can't be sure. That four piece bonus allows me to run off three envenom's in a row and a DFA. It's been a troubling decision.
