That's why elo matters. It only drops substantially if you lose against a bad team. For example there is me. My highest elo in trials was 2103. Right now it is just under 2000 I believe. Last week a had a really shitty day on Monday and lost 4-5 (what should have been) easy matches. This made my elo drop like 200 points because I was ranked so high and lost to lower people. It was 1893 at its lowest last week. Now I got it back up because I have been playing well and I should hopefully get it back over 2100 next week if I play well
