Shockingly Unfair Match Ups in Teambuilder

So I was doing teambuilder with some friends, I was gold 2 last season, one was bronze 2, everyone else is new and under level 30.

We got matched up against THESE guys, see in these two screenshots. We did not stand a chance against them. Diamond and plat players with hundreds or even over a thousand ranked wins?! Every single lane was losing hard from beginning to end because of the VAST skill gap and knowledge of the game. It was not fun for any of us because it was just a one way fight, the other team probably had fun wrecking us I guess.

This just started this patch (5.2), i was trying to check the elo difference between the 2 teams on op.gg, but both times it said I "was not in an active game". What is Rito trying to hide here?
