Light and heavy attacks, dude. Whether you believe it or not, they are classified as different attacks, whether the motion is the same or not. I agreed with you the melee alone is shallow. It's not supposed to be deep. I think you're missing that Far Cry games are sandbox games first. You are dropped into a world with a variety of tools and you need to get shit done. Melee was just one of the variety of tools in Primal. One tool. Use the others in tandem and you might actually smile for once in your clearly sad life.
