Every now and then I encounter these little teleporter devices that let me go back to parts of a map I've already been to. These things are super helpful for moving around the maps, which can actually be quite big, especially considering that, until players unlock certain movement speed skills, travel can be a bit slow (even more so if you're using heavy guns). But I don't think the game utilizes them as much as it could. There are a lot of regions where it feels like there should be a teleporter, but there aren't. One thing I really like about the rougelite game Dead Cells is that they really make good use of teleporters to allow players to easily re-visit portions of a map that they've already been to. It might be a worthwhile idea of WH4K to do something similar.
