[2021] The Moonfire bow and passives

So Kerillians passive 'arrow storm' that gives her twice the base maximum ammo capacity is one of the main benefits to playing waystalker, but the moonfire bow has no "ammunition". So therein lies my question, does the energy count as ammunition meaning that the maximum energy on the moonfire bow is doubled when being used on waystalker, and being refunded (somehow) by Kurnous' reward, or does it remain the same on all classes regardless of the passive. I think it makes sense that waystaller should have a slightly lowered energy consumption per shot, since her role is mainly as a ranged special killer. it seems that taking hagbane or longbow with kurnous' reward just seems to be more beneficial, rendering the moonfire bow somewhat obsolete on waystalker, I feel this weapon is only really useful on handmaiden or perhaps shade because of their limited ammo availability, maybe the DoT would be useful for charging cloak like hagbane is, I doubt it interacts with "exploit weakness" or "bloodfletcher" though, I feel like shade has better alternatives to the moonfire bow, ie volley crossbow or hagbane. From the early gameplay I have seen thus far, I haven't heard about there being any difference with using the moonfire bow on waystalker and how it interacts with passives. Anyone able to comment on if they know? Or will we just have to wait and see?

**Edit : Do after watching more gameplay, the double ammunition and kurnous'reward don't affect it, as expected, im assuming it counts as a "poisonous" arrow so serrated shot can't be used. But bloodshot is 100% the play anyway, due to the weapon being used in between melee confrontation, and the double shot helping with confirming instant special kills. I'm also curious how the bow works with ricochet.
