With all the posts i got with the last question, i decided to re-ask with more information. I can't really tank for my guild because i am the main healer for my guild and I did mean Emblems of Triumph because it won't let me run heroics so i am stuck with random regular dungeons so the first time you get 2 emblems of triumphes and then money for any other randoms. And i tried asking my guild before but they always say Do whatever is more fun for you. And i would like to go the tank route but i dont have the gear and hardly any money, around 1400g because i recently bought my epic flying and mount. Here is a link to my character,

So i just became 80 on my DK. And thought well i'll do reg ToC, turns out i need better gear. WTF!! I am pushing 1700-1900 DPS and i know with my 80 druid healer that there are numerous people who can barely push 1500 who get that dungeon. So I have been doing the LFG thing cause no one does pubs on the server except for raid sometimes. Well takes me hours to get the group and then do the dungeon and come out with no new gear. Yes i know the first one each day gives me 2 emblems of triumph but that means i must wait atleast 10 days to get a neckpiece. So should i just stick out and stay dps or go tank and try and collect dps gear on the side? Or are there any tips you got for me to get better gear?

Any assistance is much appreciated!
