Ruix: Ive been spec'ed Unholy the entirety of my undead life. I haven't had a chance to tank an instance but I have tanked elete mobs and groups of mobs without a healer or dieing. What sort of tanking advantage does Frost give me?

Frost isnt a DPS tree. Blood and Unholy are the DPS trees (respectively). Frost USED to be the Dual Wield (DW) tree but blizzard is going to effectively tear that idea a new hole.

So what tanking perspective does frost offer... other than Sap attack speed (AS). Is it single target tanking or multi-target tanking?
