Why you crying about kids who bypass when it doesn't affect the strike in any type of way? If the kids wants to bypass and rush the strike let them and don't cry about it. Either leave the game, kill the enemies on your own that doesn't need to be killed to complete the strike, or find 2 other kids to play with that wants to do the same thing as you. Just play the game and have fun instead of crying over the forums about other kids that plays the game in a different way then you.
