Check out my DK specs, they are 21/0/50 and I really like it. I love the ghouls, they rock - they have like 17K hps each! I don't have AMZ, but it's not really that useful to be honest (it's just too expensive as far as points). I can pop AMF ever 45 seconds though, which gets me out of MAGE aoe.

I do pretty well in BGs and can keep myself healed with rune tap (with glyph) and mark of blood.

They are also really well speced for Arena 2v2 and 3v3.
