Well, I finally tanked something on my baby DK.
A mainly blood spec that is mainly for leveling/farming. I know I could do better but as I said it is mainly for farming and I run dungeons when I get bored.
I like the style. Was fun. Putting up diseases spreading them and tabbing through mobs was fairly effective.
Was using Pestilence and BB on AoE pulls to good affect.
The single target rotation was even easier.
Had some loopiness when I would use DnD as then my rotation got a bit off. Also I may let diseases fall off as I hadn't gotten DoTimers set up and still don't.
Also I kept trying to hit Swipe which didn't help. But overall I like the style. Was a pleasant change from druid tanking. More buttons to push is fun for a change of pace.
