You would think, but the game compensates for it, to "keep it fair" or something like that I've seen thrown around on forums and socials, I have seen people with the high ping markers get insane amounts of kills in Breakthrough, and I've dumped half a mag or sometimes full mags into them for them to turn and kill me. Literally the only way to 100% guarantee a kill on them is with explosives or catch them with a sniper headshot. When you join a match and see a level 1 assault with 90 kills and 0 deaths you know its fishy.
