Add more ranked modes
I'm so sick of this community and company constantly defending boosting and smurf carries. They can easily fix the problem by making SOLO queue it's own rank and party queue another rank. Ever since coming back, I'd say every match I queue into it's smurf/boost roulette, whether they're on my team or the enemy team or both.
Level <50 accounts queued with a level 300 account. It's easily solved by making two separate queue system, one solo and another party. You want to be boosted? Go ahead, show the world your party queue rank and 5 kill average games. League of Legends has flex queue but in valorant it should be restricted to solo not duo+
People who make the argument of account sharing for boosting instead of party boost, note that account sharing gets detected more often than you think and results in a permanent competitive ban or account closure.
This won't solve the smurf issue but overall most smurfs play to boost and if they solo queue their MMR quickly adjusts to their accounts.
I think this would be a great step towards fixing a major issue without causing a huge loss of a player base as a opposed to more serious systems like ID verification. Which I think would completely solve toxic smurfs, trolls etc. ID for all accounts you create, therefore all accounts are linked, you get punished across all accounts.
