What is my progression path from here? I'm feeling a little lost.

My friend and I are level 92, we've been plowing through T15/16 maps, all with max modifiers. I have the towers popping breach on a lot of the maps that we're doing, each with 2-4 affixes each.

We are not getting anything we can use for gear, nor are we getting many things we can sell. Our divine/exalt drops are scarce, and we're hitting a point where we need to get better gear to push the Arbiter of Ash, etc... but we just don't have the currency to get it.

I'm stuck on what to do, or what I'm working towards. How do I get enough divines to get better gear? What exactly should I be doing to push into endgame? What even is endgame?

We're loving the game but we're feeling bummed out that we don't know what to work towards, or how to level up our gear. Any info greatly appreciated.
