I’ve always thought and have said several times that the simple solution to decay is to not allow players to decay below a certain threshold. If a player goes on a hiatus and lets the decay kick in, that player should decay until bottom of their tier. Diamond 1 taking a break? Lowest you drop is D4. By the time you come back a lot of people would’ve caught up to you and you’re still strong enough to compete there. You get the idea.
