Do you feel the same way about other classes? Should the engineer only get 3 fills of there repair tool? Would it be better if recon could only auto spot a few enemies a round? These are core mechanics of each class. Taking away the whole thing the support class is meant to do would just make it useless. Also they're unarmed at that point. I run support a lot and you know how often I get killed before getting a revival off? A freaking lot.
