I think that RIOT needs to do a better job of showing us that they're making progress in turning troubled players in this community around. These statistics don't say much more than "join the tribunal process"...
Thoughts on these statistics from somebody who votes in the tribunal:
-Offenders Lose Games: What is there to rage about when you're winning?
-Offenders Make Bad Team Mates: These statistics are eerily similar to the Offenders Lose Games statistics...maybe because these players are raging at their team mates when they're losing...so naturally the guilty party is going to get reported by those very same team mates that they raged against?
RIOT, use infographics to answer the questions that Summoners really want to know about:
Are judges actually taking time to review the cases? or are they just auto voting?
-more statistics on the average amount of time that a summoner spends reviewing cases each day (minimum of 15 minutes as you must look at each case for at least one minute)...this would show people who are crying about the tribunal system that people actually do read the cases that are on hand
How many active users have been punished by the tribunal?
-I don't know about other summoners out there, but I don't really care if little Timmy who made it to level 6 and then plays his account one per month is a good community member...I care about regular users, people who play this game every day (or close to it)
What is the mean level of summoners who ended up in the tribunal? What sort of matches end up in the tribunal the most?(ranked, draft, dominion, summoner's rift, etc.)
Etc.
Until RIOT starts asking the right questions, they won't be able to come up with a proper solution to troubled players in this online community.
Please RIOT, show us that you fully understand the problem before showcasing your "progress".
