Make second playthrough faster by revealing the maps

Now i understand why a full on campaign skip is a no go, but theres no reason why we should play through the entire campaign every time we make a new character.

So heres an idea that makes it much less of a slog.

Just reveal the map. Thats it. After players reach the endgame on their first character, the maps in the campaign should be fully revealed for every new character someone makes, so players can see where everything is.

This way, we still need to go through the campaign, but it wont be as much of a slog as before.

I believe this is a win-win for everyone.

Wouldn't this just be another incentive to rush through the campaign?

From GGG's point of view, the campaign is the game. I doubt they're ever going to add ways to skip it. Otherwise, they would have just made a mapping game.
