Considering that normal Rahabkor (much easier than EZG) drops a bunch of things, including heroic thariel, shredder aura, and a bunch of vanities, EZG bosses need a wider range of loot drops. Also, it seems like broken spirit stones are very expensive right now – while this might just be because of demand for new spirit weapons, they should be more easily available since those items are meant as a cheaper alternative for mythic set. Maybe a hunter elixir for those spirit crafting pieces could be added as an EZG exclusive drop?
