Ok, first of all, I’m gonna disagree with how lost halls whites have no meaning, because they are still rare. While the chest event increases the amount of halls raids, the chests themselves still drops shit loot. In addition, about 100 people enters a lost halls, less than half finishes the void, and one out of those can sometimes get a white, so that is a quite small percentage of people, and not counting deaths and stuff because they do happen at times, I have had a failed void run where we had about 30 people but when one platform collapsed everyone else panicked and moved elsewhere and the void eventually failed due to overspawned minions. So no, lost halls aren’t exactly easy for the majority. It still requires a lot of attention and you have to watch where you are going and can’t just tank everything, so it is still quite an intense experience, (MotMG aside).
Also, I think you might be mistaking about the fact that lost halls minions can just be mowed down by 80 people, unless it’s 80 hackers I really don’t think that’s how it works. Try to do a full skip without mystic or knights with 80 people and you will quickly find yourself be the only one left soon or later lol, unless you are very lucky. If everything can be mowed down so easily then why in full skips brain tricksters are needed and required to stay behind and keep enemies out of the boss room? And why does the RL have to tell the group to stop and go in different rooms when there is over 100 people? I mean couldn’t they all just run into an oryx room and kill everything lol? I have had a failed MBC run where a crusade commander was dragged into the boss room and insta popped 3-4 people, and we went from 60 people to 20 in 10 seconds. Same thing when you get multiple enemies dragged in one room while clearing, so no lol, and there is also hp scaling.
While what you are saying about players should deserve their loot based on their skill is true, the majority will not find that to be very persuasive, everyone want the best possible loot they can. And in the cases of event white, that’s not true either, a shatters soloing world record player could spend months grinding for an event white and not get it lol, and I would say that jugg is probably better than most of the lost halls whites.
The problem is, people will not back down from something because they aren’t good enough, they will try to seize every opportunity possible to get the best loot in the easiest way, once they have gotten it then perhaps it is a different story. So instead of capping halls you might as well come up with another end game dungeon that is much harder than the lost halls and would give even a 100 man discord raid difficulties lol.
So perhaps instead of forcing down the number of players you could increase the difficulties.
