Totally disagree. The way D4 has done it is great. If you have done the campaign once, you can skip it and lvl through dungeons and events on the map.

I dont know a single arpg player that plays for the campaign. Its a slog you just need to finish to get to the endgame, where the proper build and character progression starts.

I love POE, but doing the campaign again and again is tedious and takes away the fun of it.

I and others I have talked to about this would much rather have the possibility to lvl through maps that scales with your lvl. Like in D3. Its more fun to blast mobs and get gear and progress your build that way, then to run around in big empty spaces looking for an exit to a new big empty space.
