SBMM In Ranked Open to Litigation

Well, something was up this season. My winrate is usually set around 5-6% every season, this season however it has magically increased to just below 10%. I didn't become that much better between s8 and s9, that's for sure. I haven't changed anything on my end. Leave as many games as usual, soloQ Lifeline mostly, play largely the same guns. So either the game gave me easier enemies or better teammates, both not something I noticed though. Or low profile being gone had an influence, as you actually now have a (small) chance in 1v1'ing all the Gibby crutch players. Don't know, but my skill certainly didn't improve that much. I just think that such a relatively large shift in winrate seems a bit odd.
