So I'm playing my Operative, been wanting to play it forever, loving it. For now, I have all 11 points into the medic tree, however, I've heard that for leveling, it's not great to fully spec into healer, just the first few points, which makes sense in most MMOs I play. My real question is that, once I have enough points in the Medic tree (which I think 11 is enough with the Probe), is it best to put the rest of my points in Concealment or lethality?
