I just started playing on a stam DK and managed to have some good moments with him (or got lucky with the enemies I fought). In a few of these clips I am running 5/1/1 without the Undaunted passives, but switched to 7 heavy in some of the other clips. I didn't have all of my morphs yet in some of the clips as well. I think I was running Dawnbreaker unmorphed and Power Bash unmorphed in some parts of the video. Let me know what you think and how I could potentially improve my play. Those vigor ticks though!

There are no spoils here but death!
