Frost tank Runed band of kirin tore worth it ?

[Varlak]

Heya I'm not raiding yet and well I don,t know if I will ever be able to get a tanking spot in a guild. So I am wondering if getting the runed band of kirin tor would be a good thing ?

The agility one barely has anything a tank would value. The strength/stam would up your threat output if you're having trouble in that department. Basically, there are better options out there for tanks that wouldn't require you to lay out all that gold if you didn't want to. I wouldn't recommend it but others may have a different opinion.

its junk for tanking, if you got gold to spend buy primordial saronite and craft yourself some sexy boots or legs.
