Yea, I was referring to feint as the 3rd ability, as some people are using it.
I don't really consider myself a hardcore player, but I do check in with threads like these and see what other people are doing to maximize their dps, to make sure I'm not doing something totally wrong.
Judging by those parses, and my own personal experiences so far, I really feel like personally I'd probably be better off just only using it at the pull. It feels like a lot of extra effort to mess with it in a fight, and I could totally see myself missing some mechanic or something and getting myself killed because I was trying to juggle extra buttons at a hectic time for a minor dps increase.
