You asked that question and I thought "Wow, this guy should know the answer to this question."
But it turned out that your signature is very misleading and you don't have the gear your signature advertises.
On topic: Because 2H costs 3400 for a weapon, DW costs 4900 for a pair. Elite costs 6800 between both 2H, Elite DW costs 9800 total for the pair. Not only that, DW Is way easier to run yourself out of resources and then you're stuck for a few seconds not doing anything.
To Supplement: STOP USING MISLEADING SIGNATURES >
EDIT: Off Topic: Asheriah, I love that talent tree. But I'd love to see a level 75 talent that gives us a third rune of each type, and makes it so up to 2 runes of each type can refresh at a time.
