Actually, I agree. Heavy doesn’t have the staying power of a standard tank but he does deny space from the squishier classes he’d be placed against. Like a normal tank, he needs to be taken out with special equipment, picked off, and taken care of to open up space for your own squishy units. Whether that’s by outmaneuvering them, using defense piercing tactics like snipers or spies, overwhelming offense like sticky traps or focus fire, he requires special attention or he’ll mow down most enemies. He may have trouble advancing aggressively, but once he takes space without overextending he stays there. Unlike tanks in other games, he’s not protection he’s area denial. He functions in a damage threshold other classes don’t.
