AymCTL Its hard to say since the issue can be caused by a connection issue, (either from you, them, or even the server), where on their side, you were out in the open when they had fired at you.
However, if you believe the Octane was cheating, I'd suggest reporting them for "aimbot", (and maybe for no-recoil and/or wall hacks assuming the Octane also had perfect aim and/or was tracking you through walls).
While the reason why I wouldn't choose "gameplay exploit", is because that is when a player uses bugs or glitches to gain an unfair advantage, (such as when Fuse players were able to bug out the Trident to become invincible, and when Revenant players were able to glitch out their ultimate to become unkillable).
Oh, thanks, so that's what an exploit is referring to. That's good to know. I have heard about those things happening before from Youtube videos, but have never witnessed in in-game. It sounds like aimbot would be the appropriate option, then they can determine from there if it is a connection issue. I didn't know a connection issue could cause something like that to happen. It definitely is weird when you see things like that.
