ELO ranking VS. League Ranking

I just want to use this post to ask about Chess.com's matchmaking on a technical level. I was just wondering if the system not only bases the "random" opponent on ELO, but also on your league rank? The only reason I would think this is that I find myself after focusing league over ELO to boost myself to the champion league, I found myself constantly losing matches and going down some 200 ELO points as a result (although there had been a summer break in between both instances where I avoided chess for a few months.) I just want to understand how the matchmaking works and if I really am facing more skilled opponents overall. I also just find myself constantly winning against friends on real boards and online who all have some 1-1200 ELO (although once again, they may just not play much) so i'm curious if i'm just complaining or this argument has some factual backing. And if this is true, could Chess.com add some kind of "Casual" mode where you literally play some random opponent regardless of ELO and stuff, but ELO and trophies aren't gained (Or it is ELO based matchmaking, but you cant lose ELO from a loss) just for people to improve against actual people at no risk. I just feel like the bots can only do so much in this respect, and there is an actual difference when playing real people, who make mistakes and have some sort of psychology. (This could also be some 4 player + Variants mode)

That's all I have to complain about.

Pretty sure you are matched only on elo. Also, if you do a custom search for an oponent you can toggle off "rated" so the result won't effect your elo (not sure about league but probably won't effect that either)

League of Legends Rank | Chess ELO
----------------------|----------
Iron/Bronze | Under 1000
Silver | 1000-1200
Gold | 1200-1400
Platinum | 1400-1700
Diamond | 1700-2000
Master | 2000-2300
Grandmaster | 2300-2500
Challenger | 2500+

Explanation:
This table represents an analogy between League of Legends ranks and Chess ELO. It's crucial to understand that this is not a direct conversion. The skills, player base, and structure of the two games are fundamentally different, making a perfect one-to-one mapping impossible. This table aims to create a reasonable and intuitive comparison based on several factors:
 * Chess ELO as a Baseline: Chess ELO is a well-established rating system, so it serves as our anchor.
 * League Ranks as Tiers: League's ranking system, while different, also creates tiers of skill. We're trying to align these tiers roughly with chess ELO.
 * Population Distribution: The number of players in each tier is important. Lower ranks in both games have many more players than higher ranks. Our goal is to create tiers that feel like they have a similar rarity.
 * Grandmaster/Challenger as the Peak: We equate Grandmaster (2500+ ELO) in chess with Challenger in League. These represent the top players in their respective games.
 * International Master Analogy: We've aimed to make the League Grandmaster tier comparable to an International Master (IM) in chess. IMs are highly skilled but below Grandmaster.
 * Other Ranks as Stepping Stones: The other ranks (Platinum, Diamond, Master) are placed as stepping stones between the beginner/intermediate levels and the top tiers.
Factors Not Accounted For:
This analogy doesn't account for several key differences between the games:
 * Teamwork: League is a team-based game, while chess is individual. This makes a direct skill comparison difficult.
 * Mechanical Skill: League requires significant mechanical skill (e.g., fast reflexes, precise mouse movements), which is less of a factor in chess.
 * Meta Changes: League's meta (most effective tactics and champions) changes frequently, requiring players to adapt. Chess has a more stable meta.
 * Time Commitment: Reaching a high rank in League often requires a much larger time commitment than reaching a comparable ELO in chess.
In summary: This table provides a helpful analogy for understanding the general skill progression in League of Legends relative to the well-established Chess ELO system. However, it's essential to remember its limitations and avoid interpreting it as a precise conversion.

I made this with the help of Gemini AI from Google, hope it helps.
