@underwood it isn’t isolated and it’s why I stopped playing the game. Good luck.
It's honestly, the reason a lot of people stopped playing the game.
In past titles, if you had a bad connection, that was on you
if your connection got interrupted, you would rubber-band on your screen, while appearing to others, to either not move, or move slowly in 1 direction monotonously.
But in Halo 5, that person's bad connection is on everyone else
Instead of rubber-banding on their own screen, now they just teleport around on everyone else's
It's a very unfair system that caters to the laggers and only gets worse as the game gets later and later into the lifecycle.
It used to only be the 1 occasional person with a very weird connection, but now it's "leaking" into just regular gameplay...
Not as bad as the "full on teleporting" guys, but there's usually at least 1 person per game who gets these "mini-skips" every few seconds (looks kind of like a random 2x strafe speed), which is enough to turn the tide of a battle between 2 equally skilled players.
I've even played against 1 guy who figured out exactly how to abuse it -- he intentionally throttles his connection, but has an "un-throttle" mechanism set up to be tied to his shooting...
That way, his position on the map is uncertain to the server when he's just walking/sprinting around, so he appears to be teleporting around to everyone else... But the moment he shoots his pistol, the connection snaps back to normal for a few seconds, so his shots all register in that brief period.
I couldn't believe what I was seeing at first, it's extremely consistent. And the "throttled" state was so intense that it wasn't just the normal short teleports, but giant leaps to the point where he would completely disappear from view anytime he gets shot... then re-appear beside you and get a perfect 5 shot before you even have time to turn on his new position.
