Congrats on the set! That's interesting that it's been on farm so long for you guys and the set is finally complete.
Ursin isn't exactly the most progressed server in the world - we've had our first two Illidan kills in the last month, I think. The Horde guild (Teh Slax) had a set after its first two kills, from what I hear. I don't remember exactly when their first kill was, but they can't have more than 3 or 4 by now.
