Waystone drop chance

I had tested again with T1 Rare waystones with 90% drop chance (on the waystone itself).

The drop chance seems to work fine when you run T1 nodes on atlas and it drops waystones by killing any mobs so I'd pretty much get 5 to 6 per node.

However, once I start to use rare waystones higher than T1 (T2 for example) with the same drop chance 90%, I'm not getting any waystones from regular mobs except if I'm killing the map boss on the node.

There is definitely a bug.

(unless this is something by design that I missed from the patch notes)
