I don't get the point, Ninja did some really good shots in the game, I'd only say that he risked a little with some of his last grenades which were close to sitting.

Besides, there's nothing wrong with repeat. If I can hit my opponent every turn for 30+ HP with the same shot, then it's only his fault for being so reckless not to move away (especially considering that nowadays BnGs are predominantly played with infinite teleports).
