Because being held hostage in a League of Legends game sucks. Rather people leave asap, and their lp in ranked will fall wherever it lands. I queued to win - and thus once winning is not possible or projected not to be possible, time to FF.
I’ve run hundreds (if not thousands) of keys since Legion and have never left a single one that wasn’t a full-group decision to quit. I’ve stayed and completed a key after two hours and >110 deaths. And I am completely against leaver penalties.
This is a much bigger deal on tyrannical, too. If a group was hypothetically willing to take whatever time was needed to complete a dungeon, they might complete it just through attrition. But tyrannical bosses are a hard stop if you don’t have the dps. Don’t blame you one bit for bailing on those.
The issue is in a perfect world people would apply to the level they know they can play at. The issue is you have people that aren’t performing or don’t play well enough to get to the level they apply for.
I have timed 20+ keys on my 480 rogue. I’m not going to apply to 20s on my 459 hunter. I could probably time those keys in a guild group but it’s not fair to the pug group for me to try on my hunter.
Yeah, that part’s really tricky. Not sure how that could be addressed that wouldn’t also result in people being able to remove someone from the group at the last minute, preventing them from getting loot.
Punishing leavers will never work. The other players aren’t bots, you can’t make them play with you. A much better solution would be to incentivize staying. Maybe give full crests whether you time or not since failing the timer already gives less loot and score.
And M+ leavers is such a rare thing now that it’s not worth spending more effort on. I’ve had maybe 3 keys across all my characters fail due to leavers so far this season.
Arguably it’s the only time I could see a leaver penalty being valid (they left costing you both loot and time in a dungeon you could otherwise have timed).
But - it’s such a narrow example of when leaving is actually detriment that it’s not worth correcting.
Especially given if you can 4 man it - there is little reason for anyone to leave unless something happened where they had to go.
(It only happens once maybe twice per expansion for me).
