I can't say I've ever seen one of those psycho guys and said to myself, "Gee, I wish I could play as one of them!"
However, after looking through the skill trees, he does seem to be an interesting character and I would like to give him a try at some point. However, I won't be picking up the new class at this time. I might wait for the price to drop. I'm already going to be getting the next expansion as part of my season pass and I still have yet to finish the 3rd DLC, so I have plenty BL2 to keep me busy for now. Plus the idea of going through the main storyline with a new character again is not that appealing. :\
Watching the video, that's almost exactly how I normally play first person shooters, so I'm interested in Krieg.
I still don't own BL2, but maybe at the next big sale I'll pick it up.
@adym Id wait till the Game of the Year or as you say, a sale. Reason is the base game + all the DLC will run you about $100 so waiting is good :D
