This is the spec i was thinking about. http://www.torhead.com/skill-calc#500MMZfMrRrhddGoZMM.1
In my opinion, the build compliments itself. I feel that Zen Strike and Master focus really compliment each other. Along with Effluence and swelling winds, i.e. why wouldn't you spec into something which is free and gives you more damage. And Gather Strength, although situational, is worth due to the amount of slows and roots in the game.
However, this stills leave me unsure on what secondary stats to go for. With the new stats on BM gear would it be possible to just leave the mods as they are and just go full BM?
