You see armor lock , when someone uses it against you it is annoying yes but that is only because you are impatient and can't wait for the kill. It doesn't do anything else. When you use armor lock though, it is pretty good though since you can nade spam and not die not to mention you can also survive when you are about to be killed. It's pretty awesome. There is no real reason to dislike armor lock. People usually hate it because they aren't good at reach and dislike it when someone uses armor lock against them and the opponent gets the kill. They should have included it in Halo 4. Halo 4 was a pretty good and unique Halo game too tbh.
