This thread is dumb and non-specific. You're not talking about Scoundrels/Operative -- you're talking about one specific spec line. The suggestions I've seen in this thread border on inane, in some cases. The very clear lack of understanding shown in comments like 'don't let them use their cc from stealth' pretty much disproves any idea that the posters did anything other than die once in a WZ (probably to a fully geared and buffed Concealment Operative) and then come here to complain. Let me clue you in: Concealment Oprative damage is based around Acid Blade and Hidden Strike -- the knockdown is something you spec for with Hidden Strike. Once the Op/Scoundrel is in combat, he or she cannot re-stealth, outside of a 2 minute timered ability. What's this mean? Pretty much, the guy who kills you is going to, in turn, get smashed by your buddies, assuming you have them. This is why I don't spec my Operative Concealment -- it's all about killing one person, then dying soon after in any sort of group scenario. I prefer adding something to the team besides killing stupid people that wander around alone. Basically, this thread will continue for the life of this MMO (unless Concealment is nerfed so hard that no one uses it). I don't care either way -- I'm specced Lethality and loving it.
