My guild is clearing out normal BRF before we do heroic. I currently have helm/chest/gloves as mythic HM, pants and shoulders as 655... but I am not planning on using the pants tier piece as it is not on my BiS list for arcane.
Do I replace the mythic 3 pieces I have with normal tier for a dps gain as arcane? If it's not a dps gain would the heroic tier be?

Thanks in advance.
