Do you do PVE operations on your operative? Because weaving in rifle shots into your rotation post-1.2 means your already low sustained DPS before the patch is now complete garbage post-1.2. Sure, you keep your energy up but you sure as hell aren't pulling your weight in dps terms. Concealment spec is simply not viable if you wanna run HM or Nightmare ops...the energy management aspect is simply broken due to Bioware's retarded change to backstab. You either burn your energy trying to pull your weight in the ops group or you sit there doing a pew pew worthless rifle shot every so often while your guildies are probably shaking their head and muttering under their breath how worthless Concealment Operatives are as the boss enrages and wipes everyone. I can't speak for Lethality spec since it really doesn't appeal to me....my Operative is now reserved for healing while I get my Marauder to lvl50 for dps.
