Map sizes feel too large, some thoughts why

Maybe it’s both.
Bigger Map.
Slower/Not many move skill.

Just a way to slow down the game and create a bigger Act time:)

I could not agree MORE! More time spent running aimlessly across a map does not equal more engaging gameplay. It just feels like content added for the sake of content, and only serves as a detractor from wanting to create another character.

Another possible suggestion (in case the map size itself cannot be addressed) would be to consider adding more engaging content to the campaign maps? If the maps stayed the same size but had more side quests with mini-rewards hidden throughout, it wouldn't feel so pointless running through a map where the only goal most of the time is to just to get to the other side of it.
