Update. Parse blue in Savage raid [First-time mind you as a DRK] and parse purple in Extreme... [Also... first... time]. I can now confirm, that I wasn't kicked [The extreme party kicked someone else...], actually did more damage than the other tank as the MT. Now came to the conclusion that not only did my "3000" rule actually make this class easy. I also learned this class is 95% brainless. the 5% only is used for using TBN at the right time.
Also, if you want tips on how to play the class Aizen, I wouldn't mind giving a pointer or two.
