One of the biggest issues with the idea of bringing back the Tribunal to deal with trolls and intentional feeders is that players are sorely unreliable at discerning legitimate trolling/intentional feeding; people will eagerly vilify someone for simply underperforming, since they'd rather push blame on someone "intentionally" ruining their game rather than face the possibility that they might have been a factor in their own loss.
To that end...
...its rare to go more than 2 games without having these type of individuals in a game.
I really doubt that you're dealing with trolls or intentional feeders nearly every other game. It's extremely unlikely that you'd legitimately run into trolls and the like so frequently, and even if it were the case, one would think you would take a break and wait for another time to play.
How is "this" so called algorithm more efficient than tribunal?
Well, let's start with the obvious. The Tribunal required players to function, and not many people actively cared to weigh in on Tribunal cases. Whereas the IFS doesn't need people to review and deliberate and vote on people's behavior - it just receives a report, reviews the behavior, and punishes accordingly.
On top of that, not needing people to review the behavior means that the IFS is infinitely faster than the Tribunal could've ever hoped to be. The Tribunal was slow as all unholy hell (not helped in the least by the low player participation) and built up a massive backlog. The IFS works through far, far more cases than the Tribunal did and in much less time.
And the Tribunal at one point had to be incentivized through Influence Point rewards for reaching a majority vote - and that panned out terribly, with people simply mass-voting to punish for the IP gains. The IFS avoids that inaccuracy and the need to be incentivized, because it's programmed to just work.
Should tribunal make a comeback?
Frankly, no. The Tribunal was iceboxed for a reason, and it's an outdated, inefficient system. And in regards to trolling and intentionally feeding cases, I would much prefer an automated system that errs on the side of caution than a system that allows players to decide whether or not something is trolling/feeding.
The system we have right now could certainly be much better at detecting trolling and intentionally feeding, but it's certainly better than what we'd have if we let players decide.
