Oh, the old skill argument... uuuugh. Supers and abilities take skill to use properly also. It takes a different kind of skill than primaries, but it still takes skill. Some people don't know how to use supers properly at all. People that panic super, or use it just to get one or two separate kills that they could've gotten with a gun; people that don't use it strategically for zones, to get heavy, to deny heavy, for the spark, or to shut down enemy supers, etc... It's the same for grenades. Some people use them really well, others just toss them haphazardly. They may not take the same type of skill, but they do take skill to use properly.
