Waystone droprates/tiers are abysmal

My friends and I have been in the end game trying to complete T15 maps for a couple of days now.

At the start, we had issues getting waystones to drop. As we slowly progressed, we fully spec'd into waystone drop rate and higher tier chances in the atlas passive tree.

The only way we have been able to sustain is either regaling or exalting the way stones as well as putting in tablets to the towers whenever we can. In addition to this, we seek out nodes with bosses as well as grouping up for the best chance to get them to drop.

We are doing everything we can to sustain the drops, but even just dying once ever 4 or 5 maps can ruin our sustain. Even when we don't die for several maps, sometimes they simply don't drop.

Being able to reforge 3 of them into a higher tier has helped, but is not able to help sustain them.

The waystones themselves cannot be sustained, nor can the resources we're putting into them. This is greatly impacting our drive and motivation to continue the endgame. The drops need to be significantly buffed to where being fully spec'd into waystones on the passive tree actually is sustainable.
