Bronze/Silver Players against diamond/Onyx?

I guess Im a bit confuesed, but since the latest update Iam a silver player and keep noticing that my team gets put up against diamond and onyx…more the diamond then onyx, with none of those on our team. Our team would have a bronze,silver , unranked and another silver. Is it supposed to be like this now? I hope to one day be good enough to play with the higher ranks, but dont feel im ready as of yet.lol. I wasnt sure if this had anything to do with the “skilpoints” like being silver and getting a ton of multi kill medals…etc
will start putting me against better ranks. Just curious any input is appreciated…p.s. not complaining, Just want to know

Its not all the time either,just wanted to make that clear also

No it has nothing to do with multikills
