@americansteel Run across someone that built their dk well and know how to play it and you will believe otherwise. That said finding those players is not an easy task. Yes magicka dks make great support, probably the best, but a good one will be in front leading his/her group into battle.
DoTs are now 100% viable in pvp and a well played dk will produce a burst that will shock you. Whip doesn't hit that hard but when it's combined with everything else in the proper fashion it hurts and you will know it. A well played magicka dk will beat just about everyone 1v1 (is and always has been one of the best 1v1 classes in the game) and is very effective 1vX including against "good" players.
All that said its not a class for everyone. It can be frustrating and cause a lot of rage. It has a much higher skill cap (pvp) than almost any other class. It requires time, patience, dedication, practice, knowledge, and a proper build to be effective.
I guess what I'm trying to say is to make a viable mDK you need alot of time and skill to ensure you know how to play and also are rocking v16 gear with tristat enchants, something which I find difficult to do because I like to pvp and if all I do is pvp I earn no money or mats.
Many stopped playing mag dk because they were/are incapable. I don't know if you've ever played the class before but if you have judging by what you have to say about it I'd have to say you fall into that category. Sorry bud.
You must be running across/dueling some sorry excuses for mag dk (there are so so many around especially after patch). If you can't manage to avoid a wrecking blow or handle a wrecking blow spammer then you can't on any class (not you personally).
It takes me approx. 1 second to apply EVERY dot I have so that's just a dumb point. If your not canceling those animations your a scrub and deserve to die. There is plenty of burst available to a dk it is just done and applying differently than other classes. Could we still use a bit of a buff in some areas? Sure we can that point is not debatable.
Magplars are probably one of my easiest kills and the ONLY stam class I SOMETIMES have issue with is stamblade. The rest die just the same.
I'm glad you and others have this misguided opinion though as it will keep all the scrubs from playing my class and keep us from getting nerfed. So...keep being a believer.
