Here we go, and blizz dont even have to pay me.
All specs:
Strangulate: remove rune cost, GCD and facing requirement
Boneshield: make this baseline
Icebound Fortitude: Increase dmg reduction
Unholy:
Remove Pet summon CD, remove all pet spells of GCD, and remove rune cost from Dark Transformation.
Frost:
Increase Chains of Ice duration.
Overall Frost dmg needs to be reduced a bit, maybe?
Fixed your dk class for you right here.
Your welcome :P
