Can we have an adventure mode like diablo 3?

PoE2 campaign is actually pretty great. Really enjoyed the overall lore and story. Although right now i think it's been badly managed.

But even if PoE2 campaign wasnt this slow, i don't want to repeat it for every character i want to try.

It takes a lot of my valuable time and prevents me from trying new things.

Being able to respect your ascendency helped this problem somewhat. But i feel robbed of trying the other classes because of it.

Can we have an adventure's mode for out alts after we beat the campaign?

Rescaling the difficulty of maps so you can do them with a low level char and increase through it or something. I just don't want to repeat the campaign, for every new character, in every new season.
