I was hoping this would just die, but since it's not let me explain.
10 horde only have so much health to deal damage to at any given moment. 3 24 hunters are basically competing for tot. Since there are less asswipe hunters on your team, you obviously had more tot in ratio to them. For instance, if there had only been 1 or 2 24 hunters, they both would have done another 20k more dmg in all likelihood.
On a side note, there are many other threads in which to post scoreboards. Making a new thread about one, especially about hunters and 24's, is so beyond genuine trolling because you simply don't quite understand how commonplace those instances are.
