So that would take only 12 wins to rank up? Pretty much everyone will be Diamond in a few feeks then. What needs to be done is to increase points for wins and decrease for lose. Right now, I see people who only did 60-70 wins week one, never qued again and they are still in top 30, and will probably remain in top 50 by the end of season. Meanwhile people with over 500 matches come and go from top100 regularly, depending on quality of healers quing at any given day.
Just like with season 1, quing is simply not in people intersests when they reach a certain rating fast. With score adjustments they didn't fixed the core issue, and I see mostly new players with majority of top100 stopping queing.
