The general consensus of my guild/server is that operative dps is terrible. I do not agree this to be the case but I do believe there is greater than a 5% disparity between operative dps and the higher dps classes (in perfect operation conditions). While I do not have any parses to prove this, the lack of a gap closer, stricter rotation/resource systems and greater positional requirements for operatives make the disparity even larger.
Although my operative mainly raids as a healer, I have conducted my own tests as dps on a training dummy (with no avoidance on the dummy, my full rakata/black hole [with little alacrity] healing gear is viable for dps testing). I have found the following (with full class buffs, but no boss debuffs):
Concealment and Lethality are competitive with each other though would be easily outperformed by other classes I can pull around 1250 as concealment and 1200 dps as lethality Lethality's rotation is more difficult and would be even more difficult in operation conditions becuase of lackluster dot tracking on boss targets Lethality would perform better on certain fights due to greater array of ranged attacks
What would improve the disparity? According to my observations, introducing so form of gap closer (such as a sprint or rogue shadowstep in wow) and/or a small increase in damage of a common spell between skill trees (eg. shiv, backstab or corrosive dart) and/or relaxing positional requirements (such as relaxing the dependence on backstab in the rotation or removing the requirement to be behind the target).
Remember when uploading logs on training dummys that combat does not end immediately, try to finish your full rotation upon the expiration of your dots, otherwise dps values will lower. Cloaking Screen does not end combat if dots are still running.
I will try to upload logs when I am able to test dps again.
