Medic's may not be as powerful as other classes, but their speed and armor boost do make them quite good. A good medic can even solo the Patriarch on some maps due to this. And I'm not asking for all Medic's to just simply heal. Their healing is fantastic. It usually only takes one syringe and the teammate is doing well. All I'm asking is that medic's heal more often than they do. One way to achieve this is to increase the incentive to heal.
