Yeah, from what I heard Hard is just flat out unfair at parts rather than a reasonable challenge. I'm on normal and had a hell of a time in the first real dungeon after you get jobs, but after that minus trying to do sidequests/nemesis battles too early (ps the recommended levels for those are COMPLETE LIES ALL LIES) everything seems fair, though I did get two of the fancypants Norende items that reaaaaaally helped (Angel Bow/Blessed Shield) Also customizing the special attacks to target nuke weaknesses ohh yeah. I'm staying away from the handful of Super OP Friendsummons I got, that's a little much for these bosses as of now.
I just started Chapter 2, and I'm starting to take a stab at what's going on given what happened and the complaints of the internet (Ch1 spoiler/random speculation)
Spoiler:
So I'm thinking Ringabel is involved in some time travel shenanigans after Round 1 in stopping the rest of our motley crew failed because ?? and he tried a different approach entirely (though if that whole =Dark Knight thing is a misdirection somehow I would be quite happy as well, but I don't know how they'll write themselves out of that one) This would explain the similar but not exact plot details/progression from the Book of D as it happened already in a slightly different fashion. Also the sage shows up in the mini artbook with the Council of Six dudes and he's basically what Ringabel will be when he grows up but what if that's literal somehow because of said shenanigans

Now, the main complaint I heard was halfway through the game it does something interesting but is executed poorly and drags on and people wanted to just rush to the end and finish up.... what if at that point things went belly up again because ?? and you have to do a
Round 3 of the storyline? I'd probably find that tedious. This also being written by the Steins;Gate crew strengthens my belief in crazy time/dimension shenanigans being afoot.
Anyone who's beaten the game or gotten far enough to Know Better please please don't confirm/deny anything, but I wouldn't mind other speculation and people to bounce back theories off.
Also my sister will be ordering the game and getting it sometime over the weekend since it's mad sold out, so if anyone wants to add her for more slave labor 4613-7988-3902, she'll show up as Lonny, just let me know if you do so I can pass it along.
Also also the Merchant class makes everyone so dapper I really need to make my whole party them at once but then battling is MO' MONEY MO' PROBLEMS (probably)
