The entire problem with gearscore was how inaccurate it was, and how it was ultimately terrible at gauging how good a player actually is. Raider.io is far better.
Yes, some people use it to get people to boost them, and some people use it specifically to deny noobs/returning players - but those people probably would've kicked you after one boss back in the day when it became clear that your DPS is below par, which is far worse than simply being denied.
You get the point though. r.io is fine by itself, but give it in the hands of players and the results are abysmal. Informations provided are still in some way limited (but i think there's no actual realistic way to achieve that) and players read from those only what they like.
On the opposite side, i have pugged raids quite a lot and while it's the same thing, i have had way less issues pugging raids than M+, even on release day. Maybe since raids have way more people involved, the personal skill gets diluted in the bunch and there's way more leeway. Players know that they can carry a couple of bad people so they don't care much.
Generally, i don't think the M+ format helps the game. But it's extremely popular so if people keep playing, it's going nowhere. Better to buckle up and get myself into it, willing or not. (EDIT: would be awesome if all endgame was shrunk down into M+ style. Again, it's a matter of M+ and raids overlapping too much).
Non ti fidar di me se il cuor ti manca.
Raider.io is probably the only reason I'm subbed right now. Pugging without it was so bad that I wasn't doing+ in legion at all.
There's three things to watch in order of importance:
1. Number of timed dungeons above ##
2. Overall io score
3. Highest completed level of the dungeon one applies for
1 - is very important, because I've seen people who have done everything over 15 once or twice and barely anything else. Obviously paid for boost or got carried. Either way 99% chance the person has very little experience and skill.
2 - for obvious reasons
3 - I would never decline someone who is 1 level below the key they apply for if the above two points are legit. But I would decline if it's 2 or more levels lower. You should progress naturally in steps, not expect to get carried in a 20 if you've ever only done 15.
And then if I am looking for a fast farm (ie echoes) I will be looking for overgeared and "overskilled" people to breeze through 15s, that's not for anyone to progress, but to pull 5 groups, delete them and finish the dungeon asap so new one would start.
TO FIX WOW:1. smaller server sizes & server-only LFG awarding satchels, so elite players help others. 2. "helper builds" with loom powers - talent trees so elite players cast buffs on low level players XP gain, HP/mana, regen, damage, etc. 3. "helper ilvl" scoring how much you help others. 4. observer games like in SC to watch/chat (like twitch but with MORE DETAILS & inside the wow UI) 5. guild leagues to compete with rival guilds for progression (with observer mode).6. jackpot world mobs.
Right, raider.io and similar tools in the hands of players they're not meant for is a ticket to toxicity. That's a problem with the players though, not the tools - the alternative is making sure tools are weak (such as FFXIV disallowing addons overall, especially damage meters), but I think that makes for a much less interesting endgame scene.

If there was a single way to raider.io as toxic as it possibly can be for people who abuse it, this is it.
In my personal experience, the ONLY folks who want it to go away, are the folks who it prevents from being lazy and getting carried.
I will gladly take a 430-445 DPS over a 460 dps, if the lower ilvl DPS has a main with a high IO. I've seen so many piss poor 460-470 DPS's that cant even pull 40k on a boss.
Raider.io is probably the best thing to happen to WoW as far as addon's go. I cannot imagine trying to do M+ without it. Anytime I think about it, I can just assume it would be by far the most toxic thing in WoW if it didn't exist.
So, on one hand people complain about how the game is becoming less social. And then there are posts like this to illustrate one reason why.
People creating tools to segregate players so they do not have to mix. And people wonder why some are asking for more solo challenging contents.
This is not the same argument anymore.
Ofc, if you made a system that COULD account for every little detail and decide whether something is appropriate or not it would be a perfect system.
But such a system is impossible to make.
At this point you went from "simply leaving is not an accurate metric" to "let's have all the thousands of runs run thru an AI that calculates in real time 24/7 every time you even enter a dungeon".
Not even Blizzard keeps such data around, all they record is your time at the end of a run. That's it.
What you suggest is even more delusional than OP's initial suggestion.
OP's suggestion could not be implemented either but it would need much less data to be collected.
Raider.IO is just a tool. The issue is the community and it's difficult to do something about it because both sides of the coin have some legitimate grievances over the whole thing. Unreasonable demands are an issue, but on the other hand people who are clearly out of their league having unrealistic expectations is an issue as well.
