Patch 10.10 Visual Summary
Riot have responded to the community’s outcry in terms of a lack of action towards game-ruining behaviour. This patch implements the first step in their short-term plans to adjust their Reporting and Punishment system. This patch should see players receive more “Instant Feedback” reports for disruptive behaviour. More information on Riots plans to address this can be found here.
