I just recently got Thunderlord Flamestaff from heroic Grimrail Depot. And I'm wondering if it would be better to go with this + a haste gem, or keep my current weapons?(My current weapons are Dagger of the Sanguine Emeralds + Interloper's Mossy Skull) It just makes me sad, losing all of that mastery. But I'm wondering if it would be better to keep the staff with the socket, despite it having a less than optimal stat?
