Literaly went from level 7 to 3 because of faceits algorithm and ban policy.I got banned so much that i pretty much gave up and when i came back i was way worse than before and instantly went down because if i wont carry those idiots no one will.Now i bought premium a couple of weeks ago and i started training again hope it will help me get back on my old level but so far players aint much better than regular faceit.
IMO Premium has lower skilled people but maybe less toxic (some even annoyingly non-toxic while sucking) so if you and 2 friends are hard carrys then Premium is prob. worth. Other than that I feel free queue while more toxic is way more skilled (of course there is always some bots either way).
Lost 500 elo a couple days in prem queue, gained 500 elo in a few days free queue.
