Weird Matchmaking

First off, it's apparently known that matchmaking is garbage, for all types and skilled players... but this is based off of me leaving and coming back to try the game out... I'm level 7 and have hardly played (obviously).

So i have had a few games that seemed unbalanced and simply didn't make sense... but i kept playing thinking maybe it would matchmake me with players who were bad if i kept dying to high levels with high stats... or so i thought 200-300 kills was high. 

I was then matched with a friendly team who seemed to have a decent amount of playtime, but they died even faster than me, didn't speak English, and were honestly sounding very rude towards me or the game (not sure because they were not English speaking).

But thats not the worst part... the worst part was that when it showed who the enemy team was,  one of them had 3000 KILLS, one had 1500 shield recharges and one had over 400 wins. 

I am level 7, two of these people had a dagger in place of their level,  i think the other was level 40 or 50... but they wiped the floor with my 'team'.

I downed one but that was all i did the entire match,  i didn't even get out of the spawn half the time before i got shot at and killed. 

And the worst part is... this was just a public match i thought I would go in to practice... but thats not happening when you're put against people who have played at least 1000 hours of the game.

Idk about anyone else but it was the absolute worst experience I've ever had in matchmaking... and Ive played cod for years with what i thought was bad on their end....
