Look I've searched high and low both on league site and online and can't find a solid (current season 7) answer.
Scenario: After 10 promos I hit Plat V 0LP IF I don't play anymore ranked (Therefore my MMR doesn't tank to Gold V) will I decay into Gold I? If so when? How? Can I prevent this by playing a weekly ranked game?

I mean, I know it's a silly question and I should just keep playing but Plat V was an achievement lol.
