Been playing valorant for about 3 months and this is what is bothering me. I think the game does everything possible to make solo/duo players get a better rank, but for me one of the most important parts of a online game is the social interactions that you made along the way. Sometimes i just want to watch people that i dont know chatting about their experience in game to really make me feel that there are a lot of others players in my reagion.
I played runeterra for a while, got up to master which was the highest elo possible at the time, and this was the main reason to drop the game. The feeling of loneliness to not be encourage to know better other players and have a dynamic to encourage this results in the reason of most group of players stays playing is rather off-game than in-game. Besides, in valorant is very, very hard to drop your level in a new act once you reach to d3/immo because the fundamentals skills needed to reach this level (such as aim and game sense) are barely affected by the currently meta, instead of what happens in runeterra where if you stays out of the game for a couple of months you basically have a new challenge of learn to play the game again.

I have friends in bronze, plat and immortal, and what all of us says is that we needed a mechanism to evaluate our ability to play together rather than an individual system such as the elo. Besides contribute to this, a clan dynamic would increase the social experiene of the game in which we would be able to invite other players that we like to play in our team in order to expand the 5 player limitation to what is considered a full group in the actual game. And last but not least, this would encourage the valorant players to improve the tatics and comunication in game, when knowing that you're also playing against a coordinate full 5 players teams.

I sincerely can't see a reason to not have a clan dynamic in a fps game. Played cross fire for most of my teenage years and this was, by far, the most praised aspect of the game by the community players.
