I've seen a few posts, and I addressed this in a small post on twitter but I really want to make sure to be open about what's happening and why.
First, I understand it's frustrating to go from a rank you spent lots of time achieving and then get dropped back down. Rank is part of your identity in Valorant and when ranked reset occurs it can be very upsetting depending on how hard you drop. While it may be rough to get dropped, know that the entire playerbase of ranked is getting dropped the same amount following the same rules. We aren't dropping you more, or singling you out, the whole community gets hit with the reset.
Second I want to talk about the reset itself. I believe we could have done a better job messaging the Episode reset was occurring, I will ensure going forward it's included in the patch notes. It's a standard formula we now have for ranked but the rules for reset are as follows:
Every episode the highest you can place is diamond 1, and we will squish all ranks downward. You can expect to drop(usually) 1-4 ranks from where you were last episode. Higher ranks get dropped harder due to leaderboard ranking, boosting concerns, skill atrophy, etc.
Every Act we only reset the leaderboard, dropping all players to 10% of their current RR(if on leaderboard). Everyone else is only required to play 1 placement and will earn their previous rank back from the prior Act.
These rules have been in place since Episode 2, so expect them going forward and any changes will be announced.
We have multiple reasons we do a reset, and I want to make sure I make that clear so you can understand why we have a ranked squish. One thing to remember when talking about Valorant, and ranked, is that the entire playerbase is improving in Valorant all the time. Skills like default smokes, how to entry, default plants, etc. start to become common knowledge and trickle down through the ranks. In beta a Platinum player might not have known the default plant for A on Bind, but now it's something most gold players probably have an idea of in the current season(for example). You can even see this in League! Wave management is something expected of ranks above gold, and in the early seasons not even high rank players knew wave management to the level we know now.
This knowledge means that the player base is evolving and average skill is going up. It may plateau someday, but as we are a younger game it's constantly shifting and moving faster than a game that's existed for many years. This is one of the reasons we have a ranked reset. Players may be gold, platinum, diamond, etc. but kind of coasting at that rank. They may not be playing Valorant regularly, improving with the community, or they may just be doing the bare minimum to ensure they don't decay. By resetting we are ensuring that if you are Diamond in the current episode you actually are a diamond player right now. There are no questions about how long you've sat at that rank, or if you've been coasting at that rank. You've been reset within the past 6 months, you have achieved diamond in the current season.
The above point only looks at the community's average skill, but another reason is the general game balance and competitive changes to the game as a whole. Every episode is very different from the episode prior. New maps, agent balance, weapon balance, map changes, etc. will affect the communities skill levels as a whole. Again, as the point above, we expect you to prove that in the current competitive atmosphere you belong at your rank.
Lastly, it also helps us clear out boosted or botted accounts. While we will always try to combat bad actors in Valorant ranked, it would be foolish to think we will always detect all of these accounts. It helps clear out accounts that may have abused the system and have gone undetected, and if they try to abuse the system again potentially get caught in the process >:D
On a side note, I want to address the statement "Riot just does this to increase the grind to make you play more". I am the designer in charge of ranked, and as a competitive team we work out what we want to do to create a positive ranked experience. Our team does not have a requirement to increase playtime, or any expectation that we must enforce a grind; we also do not have anyone above us pushing these ideals or goals. Creating an artificial grind is a bad thing, in fact we try to avoid it as much as possible. We play and love Valorant just like everyone here in the community, we want to have a game we all can enjoy. If you make a fun game, where the players just enjoy playing it, you don't need a fake grind. In fact I would argue that a fake grind would turn players away, and maybe tarnish a fun/positive gaming experience. Our goal is never to enforce a grind, and if we could find your true rank after 1 match we would do it. Remember, the primary goal of ranked is to figure out your skill compared to the rest of the community and that's our guiding light when making decisions.
These answers don't make up for the fact it can still feel bad to have your rank taken away. That being said, we aren't taking away you or your skill. If you truly belong in gold you will get to gold, the system is designed to find your true rank based on your skill. It also does not stop you from improving, getting better, and surpassing the skill you had in a season prior. My hope is that you can get your Episode 3 ranked gun buddy, say "Man I'm proud of what I accomplished last Episode, but I think I can do better this Episode." and improve from there. At the end of the day, if you can't get back to the rank you had last Act do you deserve to be that rank now?
