So, look, don't take credit for wins and "idiots in the open" when you're a red-bar. Let me explain lag to you. Destiny servers do the matchmaking, then hand off to a peer-to-peer (P2P) connection. As I understand it the person with the best connection "hosts" the other 11 players (in this case, since you were playing combined arms). Since you had a red-bar connection, of course you wouldn't see any lag - because you were creating it. What the other players will see, is you jumping around the map (because your position doesn't update continually) as if you were "blinking." The other players can't see your actual position, don't get you on radar and, when they do see you, it is often not where you really are, because your position is not updating correctly. They can hit you straight in the face with a shotgun and do no damage, because you are not where they think you are. You often have an advantage in melee as well. So don't be an ass. Reset your router if your connection is bad (yellow or red). Otherwise you are taking advantage of your situation and are rightly being reported for cheating.

Dont worry they were just blaming lag cause they sucked. Barely any lag EVER in this game if you have good internet connection. Tell that guy to fix HIS connection.

Ya in bf4 I was playing defuse when I got message spammed by sombody I had just killed. Turns out I flashbanged him and he thought I "screen hacked" him lol. Idk what that means but I sure did get a good laugh out of it.
