It turns every game into SWAT. It's not a competitive strategy, it's an exploit. It doesn't take much to quickly press a few buttons and get results. The skill gap is more like a knowledge gap. You just have to find out how to do it pretty much. Commonly exploits that go unpunished are praised by the parts of the competitive community because it gives them a quick upper hand. It happens all the time in fighting game tournaments. The people who bother to show up to those things in person get praised for using the fastest and most boring methods that happen to be the most effective because they are usually exploits. It's broken. Also Halo isn't some sort of fighting game where we use button combos. Yes everyone can do it, but it devolves the game into a shoot first instant kill match. Which is fun in it's own right when gone into intentionally, like a rockets only or snipers only match. Or for some reason if you like swat, that too. Halo is not a fighting game. Keeping these exploits in just deprive it from it's pure form.
