I'm not exactly pro, but I'm nerdy enough to consider myself fairly good at this game. I have to kite constantly as a Monk, and my friend does the same thing on his Barbarian. This is incredibly hard too, because when I can't hit an elite mob because he has molten fire all around him, and they drop 80% of my health off everytime I get near them it is really hard for me to get spirit. But yeah, even being built as tanky as I possibly can be I still spend about 90% of the fight running around kiting.
