There has been several times inside crucible and or iron banner when inflicting damage on another player doesn't register. This seems to happen all the time with me and my friends that play. It's a very annoying issue that inhibits gameplay. It's one of the reasons I rarely play crucible except through iron banner. It happens against any other player all the time. And before there is comebacks saying to check my internet, I'd like you to know that it was the first thing that came to mind but my internet is hardlined to the router and we have some of the best (and expensive) internet you can have with the best signal and rarely any hiccups. So it's a problem with the game and it'd be greatly appreciated if it was fixed. Destiny is my favorite game and I don't wanna get so annoyed that I don't want to play anymore.
