I’m aware of the in-game feature, but it feels like it goes nowhere, it doesn’t even have a drop down menu option specific to smurfing.
For example today, I matched up against this guy, who quits 3 games in a row then plays one - its pretty frustrating when just playing to get ready for a tournament to have the ELO artificially bumped. It would be nice to at a minimum, have an option to report as smurf within the official channel which the AI can then run some quick checks through and when it see’s a 6% win rate in the 0-5 minute mark, get flagged for someone official to look at.
