If an old player returns to playing, their old score doesn’t reflect their current skill, and gives them a huge unfair advantage.
Another example:
In Hanabi, the rules changed a few months ago regarding abandoning games. As a result, the average player that played 1 year ago gained more ELO than the average player does now.
I can only really speak to the ELO changes in Hanabi, as it's the game I keep coming back to... Originally, I found the change to ELO loss for abandoning games really, very annoying, as the high ranking Masters generally only abandoned when it was clear a low-ranked Master simply didn't understand the basics of Finesse and Bluff (making for a miserable waste of time), or when a player went offline and failed to return (we generally didn't kick players out of time, because we all have RL emergencies, and turned-based is really annoying unless there's only a few cards left).
However, none of us realized what a problem abandoning was becoming for lower ranked unskilled players grinding ELO. To be honest, we should have known something was up, as it seemed like none of the new Masters in the 700-750 range had a clue how to play with anything beyond the basic conventions (and even those were causing bombs).
So I now appreciate the reasoning behind the Abandon change, even though it's annoying to those of us who weren't gaming the system. I'm running into fewer clueless new Masters, as unskilled players are unable to rise through the ranks (without straight up cheating).
In the same way, a player with artificially inflated ELO from years ago is going to be self-corrected when they start playing games again. Without an understanding of the conventions used at the 1000+ level, they're going to bomb out or get imperfect scores and get RT (or uninvited) by the other high ranked Masters. Their score will naturally decrease fairly quickly. It's just slightly annoying for the other players at the table who realized too late that the rank does not match the skill level.
The problem I have with ELO decay for Hanabi is that good former Masters could be locked out of Masters games if they're dormant for too long. It's really challenging to play with Experts when you're accustomed to a higher level of play. The former Master will find the complex clues just come naturally, and the Experts will struggle to understand. I've tried teaching Hanabi to friends & family, and I'm really, really bad at sticking with just finesse and bluff, and even those conventions are too complex for beginners.
Anyway, my point is that there's really no need for ELO decay for Hanabi. But it wouldn't ruin my play experience, if they did implement it -- unlike invisible ELO. I have found these last few days highly unenjoyable -- to the point where I am spending my free time reading through new insights on this thread, rather than playing my favourite game (AKA the reason my Husband and I both pay for BGA memberships).
