I have to say it’s a little odd going from playing a hunter to a death knight, in more ways than one. For one thing I’m used to being able to contribute to CC (yes, used to: I did hunter in BC) and now I suddenly have none! And now it’s important!
That’s okay, though, because I have many other fun buttons to play with that are still of endless assistance to the group.
Interrupts. Interrupts interrupts interrupts. Your tanks and your healers will love you. The talent to reduce the cooldown on Strangulate is well worth it. Casters standing in the back? Shut ’em up and bring ’em over. Shadowlancers doing their AoE of Healery Doom? Nope! Not anymore!
Don’t forget that you have more than Mind Freeze and Strangulate. Hungering Cold is well-nigh useless as “CC”, although I do use it when I see strays to give the tank a few seconds to get a handle on the situation. It can, however, serve as yet another interrupt. Is a mob whirlwinding and cutting up both your face and the tanks? ICE CUBES.
Last but not least is our old friend Death Grip. This does require some co-ordination with the tank, but I use it to good effect with my Cranky Tank with casters or ranged hunter mobs are misbehaving.
CC is awesome, yes, but so is making the tank’s life easier and reducing damage done to the group!
