Wasn't the intention of the tribunal system to improve the community? Well in my experience it has greatly reduced the ability to enjoy this game due to everyone thinking they can report everyone for anything.
Instead of playing league of legends, the game is now about trying to come up with an excuse to report your chosen person of blame for 30 minutes.
And usually those excuses suck, people will even do this when you have scores like 12-0 and couldn't be carrying harder or someone said noob or something.
So basically what we have now is an entire community of whiners. Some of this could probably be alleviated by allowing the person submitting the report to be punished in the tribunal, but not the bunk of it.
i like to give disclaimers before games about behaivor...this seems to slow down the trolling and people are quiet....boring but better than rage games
