THe same arguemnts went for rogues back in the day with Vanish sprint evasion. People complained bitterly that rogues would use cds to kill someone. It sounds very much the same in this case that you are using EVERYTHING to get a single kill. WHich is fine i have no problem with that. However, if people are dropping a truck on somone with CDs then sitting out 2 min or just going after people sub 50% hp, thats what rogues have done in every game with said class.
The major op thing about Ops is that most people dont know how to play this game yet. Most people dont know how to stop them. Will there be a few Ops that are actully skilled? Yes and they will tear people apart. Pugs gonna zerg and not care about whos killing the guy in the back. Then they come here or the pvp forums and say how Ops are op.
If when they nerf ops concealment the smart ones will go Healing. I look foward to the Nerf Ops healing its too good posts when they come as well.
