hey man ive got a frost dk tank named addr on thrall, duel wielding a broken promise and red sword (blah blah), ive noticed that most dk's usually use a 2h weap. for tanking which is all well and good but i want to promote the usage of dw for 2 main reasons. First, there is no such thing as a defensive 2hdr so even with your gargoyle chant your still missing out on tons of defensive rating, therefore being able to gem and chant your gear with things other than defensive stats huge bonus no?, also your giving yourself two whole extra equipment slots that will stack not only def rating but hit and parry as well something else you loose out on if you use a 2h, survivability through aviodance and damage mit are crucial for every tank espically with the new content that just arrived and in order for us dk to survive in an uludar world we must conform

Secondly ive noticed that even though dnd and rs are great for "burst" threat, your tps is much more consistent and I usually top out other dk's (and even a few pally's) on tps, and really I dont know if the parry glyb is a myth or not i dont care I still rs every 5 sec pretty much on the dot.
Rotations:
single target mob
it ps hb bs bs (rs if you haven't parried by then i mean common) hb ob ob runic burn fs rs
multiple target mobs
dnd it ps pes tab hb bs tab ob ob hb (2seconds of downtime 1sec between pes and hb 1 between bs and ob1 usually filled with rs or fs)
Finally, frost is the shiznit for surviving the fights and keeping great agro imo, no you wont ever to dmg like a unholi but now that moonkin aura and ep dont stack your really not helping your party out. And blood is nice to with all the healing you can do to yourself but I ask myself if doing maybe 2-500 hps going to help me out at ALL for some of these uludar fights? When things are blasting me in the face for 7k a sec dots? no. In the end everyone should play the hell out of however they want to play, just thought id maybe throw a new idea your way.
