Yes there are toxic players, even with a better report system, but in my opinion, I've played unranked and ranked, I totally agree that some players in unranked aren't serious at all, throw games, trolls, afk, has toxic behaviour, but it's the same in every game. Even ranked has toxic players, that's why I always find teammates in the Official Valorant Discord Server before queuing up so you know the players you play with are here to win and grind ranks (most of the time, I'd say 95%), and the higher rank you'll be, the less trolls you're gonna find when making your team via Valorant discord.
