Reporting ELO cheaters works!
After losing almost 600 points in 2 games thanks to the super futuristic and fair way of matching solo players against 3-player teams with 2 bronze and a LegI (all of three 9.5k+ masters) I decided to start reporting the whole team for cheating.
And guess what? It works 😁 Out of 9 reports today, 9 ended up with an action taken.
Since Supercell is so busy introducing new bugs and just add the rank difference guardrail also for 3-man teams is too much of an hassle, that's a good way to get rid of this cancer.
If you end up losing more than you should due to mixed rank teams, just report them.
