All I got to say is that now a days Concealment Ops are pretty much dead on my server. They are extremely squishy and while having stealth is nice it doesn't mean your undetectable or the only class that has stealth. I see Snipers lasting far long then Ops "Concealment" spec's. And with the new Talent Ghost you get a minor speed increase which you can abuse for unlimited running if your never in combat that is. But the fact remains Concealment is a dead Tree that's hardly worth playing anymore.
