it's very possible if you have decent aim, and some movement skills and the most important thing is that you need two teammates with the same skill level.
and time .... a lot of free time.
you should not carry anyone, and your teammates should not carry you, if the balance is not there then it will never happen.
one more thing, predators play on a very different level from the rest of us, movement is different, the aim is different, and their view of the playing field is different. ( of course, i mean the legit preds not the imposters who got with cheating )
and yes some people are as they say ( built different) but that is rare, the rest you get with practice, not the normal practice but practicing and playing for a long time with one of them sure will change your view of things.
one thing I noticed is that there should be a squad leader who calls the shots, where to move, and where to focus gunfire.
last season I and my friend won 11 or 12 matches out of 15 in one session in gold-plat lobbies just because we left the lead in his hands and I was only doing my part as support.
so having a squad leader who has experience and good judgment is like day and night.
this is my take on this, I hope it helped you with something
