Please increase the drop rate of Waystones

The drop rate of waystones is too low. I always upgrade my stones to rare and I clear the entirety of the maps, but even with 200% increased drop-rate I can get "unlucky" and none drop for several maps in a row. I don't think I can face having to go up to tier 5 from tier 1 yet again.

I understand that some maps have a higher chance at getting stones to drop but I feel that with a 200% increase it should be almost guaranteed.
