Map Sustain

I'm running t15, six mod, breach, abyss, irradiated tablets and am struggling to sustain maps. 30% more waystones from the atlas, and I cannot remember the last time a rare dropped a map. I've ran about eighty t15 maps and I have only a surplus of 5 in my stash. I'm not getting enough maps to vaal them for t16.

Curious if there is a trick, or if anyone else is having trouble sustaining enough maps to consistently vaal them and run t16.

Do u have Boss points allocated in ur Atlas tree? At the start T15 sustain was a little rocky for me, but as soon as I got 4 Boss points I basically never run out of waystones and get the occasional 2-3 waystone drop from bosses + an extra from trash mobs here and there.

I'm at 8 Boss points now and I'm swimming in waystones.
Also, running Powerful Boss atlas nodes is a good way to farm waystones.

I have 4 points allocated for 25% more waystones from bosses. I've not prioritized killing the arbiter this league. Occasionally the boss drops 2 maps. That's the only time I can vaal them for a chance at a t16. Too often they dropped to t14 so I don't risk vaaling when the map boss drops just one.

Not even bothered with a citadel yet. I'll go kill arbiter and get some more map boss difficulty.
Thanks

No real trick I can think of.


Then again, I ran 6 mod from the get go so maybe that?
