full auto + lag... holy shite it must be a hacked hawksaw. I routinely get killed by only 2 shots of a mida or other scouts. I realize with green bar lag and the state of crucible even though I only hear 2 shots hit there has to be at least 4 to drop me. So if half is dropping due to frame rates, take even less frame rates out of the vid and you have the appearance of a LMG in a hawksaw shell. The shots through walls is a dead give away of the serious lag being dealt with.

This. Additionally, unless they're running HCR, you don't really notice getting lit up by a hawksaw until you're almost dead.

Very well possible that's the case. I rarely even pay attention to all that anyway. I just know something killed me from somewhere and then I go about my business, lol.
