See but thats exactly why it should be in the game. It SHOULD 98% decide the round. That is what it was designed to do. That way you HAVE to come out of spawn, play for it and gain CONTROL of that section of the map. If you successfully do that, you win the round... 98% of the time, the other team can still exert large amounts of mechanical skill to outplay heavy although it is very difficult, its not impossible. Think of survival as more like iron banner and getting the heavy ammo like securing a hunt. That is what it is designed to be like and I find it infinitely more competitive than removing heavy.
