Rushing in a clutch situation

Through my past experience that I have had, when you stay in one location in a 1v3 1v2 or what ever is a very bad idea. When a team has 3 players alive they usually split them up, this is the chance to win 3 sets of 1v1s. I will rush one direction and take one guy out. After that I will go on an unexpected corner and kill the guy that is passing guy that was supposed to help the guy that you killed. Now its down in a 1v1 situation and you have 1/4th the health the enemy has, just swap corners and let the enemy fall into your cross-hair, and you should be able to win.
