Very clearly you want to reroll the socket, to any number of possible stats. eg. +AS; +Elite Damage. Exactly what you choose to roll it to will depend partly on what stats you already have.
It is just my opinion, but if you have no +Elite Damage on any of your other gear than that could be a good option. Of course +AS is never a bad thing. I've heard Area Damage is also a great option. Heck, if you are having survivability problems +1K Vit would not be bad either.
anyway congrats on the bow, it is almost as good as mine
Area Damage. Weapons roll to +24%. This is higher than anywhere else. If you are going to have it, you want it on your Weapon. But, you would need a GG one, but, you don't have that problem.
Thanks. That is the one stat I had not seriously considered. I assume this is related to the fact that Area Damage has had a significant buff in patch 2.3? ps. damage range on this bow is almost max as well. it would be virtually impossible to roll a better one than this. (3605 dps with 7% AS)
