i once again live up to my nub

6.1.4. Crit Rating

Another traditional dps stat, Crit has less baring on Death Knights than many other classes. No core mechanics require Crit to drive them (though Blood does require a some Crit, and Frost does benefit the most). Additionally, the amount found on gear is more than sufficient where necessary.
Crit Rating affects both our melee and spell crits. You need 45.91 Crit Rating to gain 1% melee and spell crit. All our abilities except Icy Touch, Howling Blast and Death Coil use our melee crit chance.
We are the only class that have a passive spell critical damage increase, under the form of Runic Focus granting us double damage on both melee and spell critical hits.
 

yeah i geared for alot of crit and its almost useless ..................FUCK!
