After seven weeks of disappointment after disappointment trying to farm myself a Hailstorm, Malygos finally put out.  So glad i no longer have to do this silly encounter despite it taking almost no time at all.  With this sword, i now have completed my totally cliche and probably overused Frost transmog set for my DK.  It really ties the whole ensemble together regardless of it lacking in rarity.  Now if only we could use 3 specs so i can begin working on an Unholy set.
