Grapple isn't as easy as it looks. You have to time it just right. People don't immediately end up in the fire, there is a cable that goes out and grabs them and yanks them to you.... who is standing in the fire to yank them in the fire.
If you kill them the ball goes to you, but if you die in the fire it just goes back to other team. Anyway, we have all been yanked in the fire but I am just saying it's not easy mode to do it correctly.
