Dowsing is currently very obtuse and not very useful. A member of my group spent over thirty minutes dutifully following around the schizophrenic pings of a dowsing rod before I told him instead to just start randomly placing down well signs instead. He found a buildable well within 2 minutes with my method.
Possible solutions:
*Show the exact location where you can build a well while you have the dowsing rod equipped like in legacy.
AND/OR
*Allow a means of fixing on a single ping.
AND/OR
*Have the pie slices from the dowsing pings stay on screen rather than fade immediately.
