So, Im in ranked and having people Unranked in my matches.

I just, and i mean just, finished a match. Our support was a Zillean and he admitted he was unranked; he was going through placements. Alright, cool. We lost because the opposing team was just significantly better than anything my team could manage. That's cool. So then I began to look and noticed that a few people in my past matches where I've lost (which.. which has been a lot ;-;) all had unranked players. Is it just bad luck for a S3 (was S2 but said losses demoted me and i've been losing a bunch from low morale ;-;) to get stuck with that? It's happening over 60% of my games and I'm tired of losing when I do well, my other teammates do well enough, but the one or two unranked players cost the whole team the game when their inexperience curses the team.
