What mod are you talking about?
Well, it doesn't matter what mod it is. The fact that you want to embarrass those who rush grab is stupid. It's a strategy to win or gain an advantage, and the point of playing a competitive game is to win.
It's a way to play, nothing wrong with it.
It makes unskilled people mad when they can't counter. Like every move that works, sooner or later people will say it's noob.
