I know this wasn't your exact point and you were more about the RNG but they are related in that they seemed to cherry pick multiple design strategies and smush them all together, but not necessarily in the most coherent way. I think a couple of patches will resolve the issue, IMHO. It is not as "we r DOMED!1!!" as many are making it out to be.
I do not think using RNG and stat inflation are parts of different design strategies or are inherently incompatible. That said, I agree the stats are kinda silly and hate JPRGs with a burning passion
The question is, does the dev team even perceive the current state as something to fix? I'm not sure the people who want even basic combat balancing are a significant portion of the playerbase, going by the steam reviews people are playing the game as a roamer and do not care.
