@Riot Let's give Platinum/Diamond players a break: Remove League Decay
Some time ago, Riot realized there was no reason to decay players from silver into bronze or gold into silver. Why can't the same break be given to platinum and diamond?
This system makes sense for Master and Challenger; there's a set number of spots in Challenger, and both are highly contested. This is NOT the case for diamond or platinum. You might brag about it to your friends, but you're not going to go pro or anything just because you're a diamond 5 player.
I already got to platinum earlier in the season. Why should I have to return every few weeks just to play a single ranked game where it doesn't matter whether I win or lose? It just adds stress that players shouldn't have to deal with. Now I'm even less likely to come back to play because I'm still burnt out from the last ranked game that I (probably) lost. The decay doesn't even mean you get matched with players who are worse to compensate for being "rusty". Your MMR is unaffected by league decay.
If you don't want to remove the decay entirely, at least remove the dropping from diamond to platinum and platinum to gold. We've already earned our border; why do we have to suffer a ranked game every few weeks to keep it? I could literally have a monkey play the "inactivity" games for an entire season without getting demoted. The only thing it accomplishes is making someone lose a game and remember why they stopped playing in the first place.
So let's allow our top 10% to take a well deserved break from league when they want to. They've earned it.
