sadly, the best i got to say to this is, this is Nutaku for you... we're not DMM...

this is typically what happens at times when different countries get the same game... they change things drastically

i've even seen it with an MMO I play called Elsword... the KR version (the original) got events that gave free +10 amulets which makes your equipment super strong and it's EXTREMELY difficult to get that far (+9 to +10 itself is less than 1% chance of success with a huge chance to get the equipment unusable or reset to +0). all other servers... a measly +5 to maybe +8... if that.....

and in the case of Final Fantasy Brave Exvius? there was the case of when we got Noctis far earlier than we should have so his Trust Mastery (something really overpowered but out of the way to get) and Noctis himself was weaker than they should have been for about a year....

Nutaku does have some greedy tactics so this isn't surprising.... All I know is that unfortunately, SSR guaranteed and Miracle Tickets is the best fight you get against RNG so gonna have to suck it up either way.

Do I think this is the wrong thing to do? Depends on how this plays out (a 1 time thing to get either kami weapon or eidolon would be messed up), but it's still up to the player themselves to get involved in this anyway (as in throw money at it or not).
