[2020] DE can you please unlink Iso Vaults from the Vome/Fass time? It is utterly nonsensical and has zero justification.

This makes no sense. Mechs don't go hiding during Fass/Vome underground. There isn't even any reason unlike Eidolons. It should always be the same if you do all three in a row, with no input from the cycle because it does not make any sense and it's just a frustrating and obtuse mechanic that punishes you for not immediately starting. If you don't immediately start when Vome is up, for example, you may as well wait for Fass.

The fact that the first two stages of each vault is a bunch of waiting does not help, Waiting so you can wait a few minutes to wait a few more minutes to finally fight some mechs and unlock the vaults, who designed this? And who decided, on top of that, to add the extremely annoying, unfun, anti-qol, absolutely braindead decision to make it depend on time cycles?!!
