No one denies that Quel'Serar is an excellant tanking weapon, but its cost and availability put it out of reach for some. I don't have one because I have never seen one on AH for a price I am willing to pay, at the moment I am tanking with BL's Defender because I am too nice to take a Maladath off a DPS class who wants it and as of yet only one Spineshatter has dropped.

And to the guy who said TF isn't good for tanking L2P, the proc generates lots of agro and it slows their attack speed, which makes healing the tank easier. It also has very good DPS and a nice speed.
