To incentivize reporting on cheater/map-hackers, as well as to promote fairness, may the devs consider to take one step forward to “refund ELO on successful cheater reporting”?
It takes time to prepare a cheater report, often requires over 30 mins to review and record a replay. And even though a report is confirmed to be a violation as said in email, it is understood that you have a lot of reasons not to perma-ban the player. The whole mechanism discourage players from spending time to report cheaters, and it is not good for the game.
