Still, for the high end DH, it's one simple way to increase DPS, and might not even be that expensive compared to an item upgrade, so I'm wondering, are you planning on getting the marquis? And if so, just for weapon or for all sockets?
I'm still debating, myself. Unless things change, I'm going to say "no thanks" to the armor sockets, but I'm not sure about the weapon ones. I think absent the 5 million unsocket fee, I'd probably lean yes. I still plan on updating my weapon at some point since mine is still pretty mediocre (by high end standards at least), and spending 10 million to unsocket is annoying, especially if I find a better weapon within a week or two.
Still, depending on what the final price of flawless square emeralds shake out, it will likely end up being around 200-250M for a 7.5k dps increase for me (2 gems) which isn't too bad of a price to pay, I think?
I know a lot of DH with good gear either lurk or post on these forums, and I'd be interested in their take on the new gem.
