The fact they made the drops so low is extremely stupid, if anything, it should have been one of the higher drop rate items, since it seems like they only make these items obtainable via one method, such as where they only had 1 Alternator from Delve, but had no Animator from Yorcia Skirmish, which to me is a bit worrying since whenever they release more Delve we will likely not see one from a Delve Boss, and in that event, most or all weapons will have multiple options for 119s as they do at other levels while pet jobs have only a single ammo choice and a single location from which to obtain it.
