Im currently a 2H Frost tank and i'm loving it. In terms of holding aggro and tanking I would say that i'm doing quite well in the early raids. However I keep hearing about Blood being better in 3.2 for tanking, and I've been thinking about it, the self healing and the fact that the Vamp move stays up for longer and that Blood gets more stamina is starting to make me think.

Do you guys think there is a significate difference in blood tanking vs frost tanking in 3.2?, and if so would it be worth using blood instead? My only worry is threat generation because at the moment Howling Blast is playing a bit part of threat generation. what are your thoughts?
