With the advent of Season 9 in League of Legends, Riot has implemented separate ranks per role. If I am Platinum to Diamond in all of my roles, will I get a separate inactivity decay timer for each of them?
It has been confirmed that each role has its own separate decay timer.
However, when you play a position, the timer is reset for that position and every position with a lower rank. Decay timer also now only applies to Diamond 4 and above.
Decay timer remains the same as last season for Master+.
