You are still missing my point. Every other class is designed to work together specific, mostly signified by the buffs and other abilities. The operatives are often times alone and behind enemy lines. Trying to stay alive, being conviencing in disguise, know when to retreat etc. You are out by yourself most of the time with little to no support. This is most of the high risk I am talking about. Perhaps the high risk high reward wasn't the best way to put it.
Ok I am about about to use an anology that some of you might not like but I think it fits. Operatives are kind of like special forces teams. They go behind enemy lines to mess with the enemy (among many other times) put they are mostly out there without support. Unlike regular infantry that could probably call for fire support or some other aid. I am not saying that operatives are the best class, just that it will be harder to be effective since you are at your best when you are on by yourself.
