Thank you Mr. Marine. I did remember one point. To me, Concealment relies a lot on stuns like Debilitate and Sever Tendon. Most Op's Bosses are resistant to this. To ask a question off of your response, Why is it that Concealment has trouble with Energy management. When I do PvP or Flashpoints, I find that my Energy stays above 60%. Does Lethality have some perk that allows for easier Energy Management?
