How do you substain Waystones past tier 10?

Every single time i manage to get a level 11-15 waystone i juice it up to the absolute maximum i can, full clear and and get 0 waystones from level 11-15 to drop and i go back to farming tier 10.

I'v also spent 20 atlas points on nothing but waystones drop increases and quantity of drops on top of having deadly evolution but that's not enough.

The last map i cleared was a T13 that i used 2 exalts on to bump the waystone drop to 280% and all i got was 2 tier 8 and 1 tier 10 stone.

I am having the same problem currently, not sure why.

To break even in waystone consumption v waystone drops you will need to aggressively use currency to upgrade them into rares with max modifier count before use. Could be my imagination but full party runs also seem essential to do better than break even.

1. Get waystone/drop quantity on atlas passive tree
2. Juice up your maps to 200%+
3. Use towers for more waystone drop chance and/or quantity
4. If you want to be sure you'll get at least 1-2 maps in return, run your juiced maps on bosses (i usually get 2-3 t15 maps back from bosses)
