The subject actually says all. Can someone tell me what does the Impurity talent actually DO? (no need to quote the tooltip by the way /grin). And the followup: is it generally considered a good talent?
Pretty good in PVE for the old DW spec that utilizes Impurity for buffing up HB though. Lots changing in 3.1 though so we will have to see where everything goes when raid parses start becoming available for Ulduar.
