I'm not sure the benefit of a Tribunal is worth the effort Riot has to put into it, especially considering that giving bans into the hands of players will always require a lot of oversight, simply due to accountability.
Tribunal originally already had a huge problem with how many bans it actually put out. Focussing on only one type of offense is clearly going to reduce the workload, but I'm not convinced it would do that a lot, as those cases are also going to be the most controversial ones (which means you need to have a lot of people vote on it until the result is clearly representative) and will only be easy to judge if there is not only very clear proof but also a helpful timestamp in at least one report. Pardons, on the other hand, effectively require you to watch the entire thing.
That leads me to the next problem: There are going to be a lot of pardons. For one because this offense requires intention, which can be fairly easily hidden. Additionally to those "pseudo-false" reports there are a lot of actually false reports in this category, where people simply hold people to a higher standard than is reasonable amongst their skill bracket.
Bottom line: Even when considering the lower amount of cases, I think such a Tribunal would work even less efficiently than the last, which in my personal opinion, is going to be even slower at dishing out punishments than the current system.
i would also suggest changing the name of the "intentional feeding" report category to "griefing/trolling" in order to better identify other forms of gameplay trolling besides just running down mid
100% agreed. I'm already happy that Riot changed the ban message, but yeah… don't know why it takes them so long to change this. I don't think I would include the word "trolling" though, simply on account of the ambiguity of the word. I've seen a lot of people use that word to describe non-serious or unconventional strategies, even if they have a reasonably high success rate. Sometimes even on account of people unambiguously trolling the enemy.
i would also like to see a change that any punishment for intentionally feeding in ranked is an instant permaban, not a 14 day ban
I think a season-long (or even permanent) ban from ranked would be more reasonable, additionally to current 14-day ban of course.
What I would find more important though, is that Riot should instantly permaban people if it's clear it was "planned" trolling, in other words if those people entered the game already with the full intention to troll rather than just overreacting to something.
I simply don't see why people who make the conscious choice to troll others because they enjoy ruining their games would change their ways. Especially since those actions are typically taken on throw-away accounts anyway.
