For the Best way 2 do this is to have a boosting buddy and create a rank match. Then have your friend search for your name in custom match and when your friend is in there, both of you just pick any characters. When the game starts up, the one who is getting the achievement have the other person quit out. That way it will count for a win automatically!!! Just do this 25 times and the achievement is yours!!! Rinse and Repeat!!!
