Look at it this way: that's 25 seconds he's wasting on gloating over a single kill while not doing anything useful at all. He's leaving his team a man down just as surely as if he'd been killed himself. Plus the whole thing just reminds me of those endless videos of idiots in fps games who spend time running over and teabagging their opponents only to promptly get shot dead themselves because they were too busy gloating over their single kill to pay attention to their surroundings...
