The good layouts might be more than personal preference though. This patch, Grinding Gear Games evened out of the experience which is gained on each map, so there aren’t maps which are much faster to perform. That being said, different builds are better at tackling different map layouts.

For example, a Cyclone build is likely to like mmoah smaller alleys, given that they can just run-down the alley killing everything and never having to backtrack.

Maps like Waste Pool and Sewer are incredibly good for these builds. Ranged builds, like Cheap POE Items Ice Shot or Kinetic Blast, conversely, prefer open maps like Dunes where one can take full advantage of your range. Finding the maps where your build excels is usually a huge boost for your experience gain.

There’s the opposite huge reason to shape specific maps: divination cards.

Most belongings in the game can drop from any map equally, but there are some map specific items. Divination cards are one. Certain maps are worth shaping specifically to enable you to farm they from high tier maps.

You get both they you want and experience, instead of having to stop trying one for that other.

The divination cards worth farming for are under your control, but popular choices include The Doctor (for Headhunter) and Abandoned Wealth (for Exalted Orbs).
