That is the main issue.
They aren't worthless because they actually have some effect. They just aren't "overpowered" which kids these days use as a standard for usefulness. Secondaries are balanced in a way so that a player can pick and choose any combo he wants and still complete 100% of all the game's content. If they were scaled stronger, eventually you'd get to a point where everyone has to have the same stat combinations or else they would be denied partys, further drifting away from build freedom.
