Sorry but the Operative/Scoundral class is broken. And i say that because PVP in general, should NEVER allow for a player to be killed within a matter of seconds.
They need to be completely reworked and given more mobility but less burst.
Any class that is solely based on knockdowns/burst is not a balanced class. And this type of class ruins PVP for everyone.
Its not a matter of skill its not a matter of adapting to situations, its not even a matter of strategy or thought.
The best most balanced pvp games like guild wars dont allow any single class to have significantly more burst than anyone, and it works like a dream. Fights are longer, take more thought and knowledge of your classes, and OMG! Strategy!
Everyone complains when the stealth classes like this get nerfed after an initial release and the people who play them fail to realize that a burst class in general is unbalanced, and broken, and destroys pvp and takes the fun and strategy out of it
