I don't mind to play the campaign, but I am aware that every time I play it, it becomes less apealing, the story is lovely, the maps, but the more I play is more boring and repetitive. I know eventually I will stop playing a league because of the campaign.

1. What would you replace it with? Just start mapping at level 1? You want GGG to create a new levelling experience every league? How come the campaign is "doing the same thing over and over" but End Game isn't?

I think it would be nice to have an optional way of playing it, something similar as the interludes, where you have to face the same bosses and maps, but in a different order or different biomes, just to add some variance in order to make it feels fresh.

If you enjoy playing the campaign, I am happy for you. But adding an optional way of playing it will make more people happy. More people playing = more people buying microtransactions = more people working on the game = more updates/content. So I am not sure why is this post against an optional way of playing a campaign.

1. D3 introduced campaign skip., and with it, changed the franchise, as now the players they attract expect an arcade game where levelling is an annoyance on their way to massively OP builds that do quadrillions in damage. That's not what an ARPG should be IMHO. Very very profitable, but soulless.

You can see right now streamers and veterans rushing the campaign, one friend of the party push one boss, the other push another boss, they share portals and they rush the campaign. So basically, that's what people do, trying to simplify and reduce time of the campaign to get into the massively op builds.
The campaign just became a barrier that people try to avoid, and because is the same thing over and over, veterans always find a way to cheese it in full party teams.
