As useful as the theorycrafting thread is, since it starts with full 660 gear it's not answering what seems to me to be the more immediate question:
What is the DPS difference between FV and EmpS at 630 (for example)? Is it negligible, or is there enough in the way of a DPS increase (say more than 1-2%) to make it worthwhile, especially when we'll start unlearning EmpS with T17 4-piece?
Can someone either point me to a particular post in that 31-page (awesome) behemoth* or maybe just answer here? A search of the forums didn't pull up anything that offers more than conjecture.
*I feel like all the thread closures are saying, in effect, "go read 600+ posts for an answer that may not be there."
