ZM actually has a lot of mounts, they’re just farmed a little differently than Korthia and Maw. Once you complete the second row in the passive skill tree, you unlock a bunch of side quest hubs, and one of them unlocks a mount crafting room. You farm the recipes, so far from what I’ve seen deterministically, but there may be some RNG ones somewhere.
So ZM farming is largely about equipment and mounts. Legendary is revered, 252 epics are from spending cyphers that come from boxes, rares, dailies, and WQs, and mounts are from doing the side quests.
Oh also, exalted is meant as a late patch long term farm, the paragon rep chests has stuff and things. They have designed it to keep you doing the weekly til 10.0/
