So a lot of people have probably been farming the new Zeinesis/Clifard from Deus Esca or the Ofz Units from Profound Darkness in hope of getting those "endgame" units that are drops only as currently we have no better units in the game aside from the Circuray and their upgraded Circunion version of units...
And I like most of the people have done multiples of both the 12man versions of the Urgent Quests/Triggers and most likely many of the 4man version of Deus Esca and the solo version of Profound Darkness, and more likely than not, not getting any of those "endgame" units dropped at all in any of those runs. Hell, in my case and probably many others didn't even get a unit to drop at all not to mention the 12 star units in a big part of the runs...
Therefore I come here with a suggestion to slightly improve the odds of the people with the "bad RNG" by hoping to introduce a "fail-safe" method.
The "fail-safe" method should be pretty simple, the Deus Esca fight currently gives players the Clifard Fuses, while the Profound Darkness fight(solo only) gives players the Union Boosters. What I suggest is to be able to trade a certain amount of said items with Zig for the units that drop from their respective bosses, Clifard Fuses for Zeinesis Units and Union Boosters for Ofz Units.
The amount of Clifard Fuses and Union Boosters needed to trade for the Units should be up to what SEGA feels like is a good amount to call it "fail-safe". In my opinion doing 20-30 runs of Deus Esca, 12man version and 4man version combined, should be enough to call it "fail-safe" for at least 1 Unit. Should be half of that of Profound Darkness as only the solo version gives Union Boosters.
This method could even also be introduced in the future for weapons as well although weapons already have many options unlike Units...
For example, here is a reddit post of a person that did 119! runs in order to be able to get the entire Ofz Units set. This amount of runs is absurd and not to mention it could have been even more if the RNG wasn't on that person's side. Not to mention the amount of money that had to be spent on Triggers which is close to astronomical!
My suggested method will at the very least give us players a way to reduce that load that comes from bad RNG much like how Scratch Tickets have a similar method of do a certain amount of Scratch Tickets and you will get an item that will let you choose any item that you want from thet Scratch Ticket...
