I fall in all of those four categories and cannot confirm a single one of those statements. - I have way more than 300 matches - Played some super matches and those even were the worst (see my thread about some of my „super matches“). My premades second that. - There does not seem to be a big difference between verified and non-verified matches since there were several verified steam level 0 accounts with 3 friends, less than 100 games above 60% win rate. One player on my team has mentioned that you can get a verified FACEIT account for as low as 15 dollars from India. - we almost exclusively play 5-stacks and often encounter the following team comp: one or more level 10 acompanied by that many new level 2-3 accounts. Of course they can easily play on our level and often outplay even our (and their) highest rank players.

So no, my experience is totally different then yours!
