If you're going to feed, don't go for vultures, there are better units you can make at a cheaper price. Vultures take a while to build too. Even if you don't get rushed, the other team could already have a good amount of gauss hogs out, when combined with a cryo or mac blast could probably take on the vultures by themselves.
This would not work against any good team, there are too many ways to stop it.
