I’ve heard rumors from valorant channels that riot was supposed to implement a in game tournament system (clash system) similar to League. Does anyone know when this is supposed to be released or if it still is going to be implemented?

I’m currently (slowly) climbing in competitive and i was wondering if refresh rates matter? I expect the players in high elo will have a 240hz monitor but I’m unsure if that is the standard. I currently play on a 144hz monitor.
