Since people hate campaign in both PoE1 and PoE2 after doing it hundreds of times.

Since people often say they don't wanna complete the campaign over and over on Hardcore and even on SC on new characters. I have thought about an idea for about an hour and I have a base idea as a game feature
I don't mind if you ignore it or don't consider it , or maybe you have other plans. I feel like the endless ledge races were very fun. What if you guys can implement (in the far or near future depending on the development time and ROI ofc) a mode
accessed by level 1/2 characters after you've finished the campaign. Maybe it could be similar to endless ledge. Maybe it can lock your character to that "Stage" or "Level" until level 64-70 (somewhere around there). It shouldn't be faster than the campaign
or it could be if you're good at it. But it shouldn't be a no-brainer as to which one you choose. Gear found inside could be limited in some way, or the gear that comes out of it can be. So that people don't abuse it. Although it could pose no problem if the loot and density are similar to
the campaign itself. The character can't exit that stage unless they reach the final level of course. It unlocks your points and stuff, or you can put skill points inside the stage. They could have special side quests or tasks that are finished on the way to the top,
that reward the points. All these things are based on how you view the game as a dev of course, they can be tweaked and changed. The stage could be a lore thing in the first town or by the beach. I understand right now if you have a high level character,
it is by design(or not) that you can find leveling uniques that trivialize the campaign when you equip them. That is your reward and that is the "skip" that you get for having a high level character in the current league which makes creating a new one easier.
That is the PoE's hidden "level boost" unlock. It's just an unwritten rule. But still I feel like people want an alternative and more randomized way to level. Endless ledge with secrets like the lab has, could be very fun as an alternative. Of course all I am saying
is just the BASE of the idea. You can work on it and put interesting things and restrictions and items (that may disappear after the run) which are parallel to the campaign.
