While playing, I kept saves before entering each dungeon, so I was able to go back and try dungeon 3 with an appropriate save. The animal-themed moves are neat, and definitely help flavour the playthough, while the other cursed items are now inconvenient enough to actually care about instead of completely ignorable. The stuns from the Choker seemed to proc more frequently than I'd have expected, and the Blinders were annoying enough to make it worth swapping up my team order to deal with the vision issue (this is a good thing, provided that everyone isn't blind).
Moved right on to dungeon 7 after that (with my latest save), skipping 6. It was... probably much too easy, actually? Everything here gives stat boosts instead of penalties, but instead of it being the case that you needed to get use the fetish mechanics and get mostly-trained to easily handle the boss, I explored around, opened a few boxes, found my way to the boss, and defeated them like two levels below cap, while most of my party was less than half-equipped with pony gear, despite a couple of hand-me-downs.
Moving on to maxing out the titles here was a real chore. I had to go considerably out of my way to get loaded up with pony gear (I basically loaded my group up with defense buffs and offense debuffs, applied them all, then sat around waiting to get kitted out), and getting to max grace actually required me to abuse oats and resets (after beating the map and getting fully kitted out with everyone, I had a combined total of 30 grace across the party). Then, actually getting the titles just required... lots and lots of walking. Which, okay, sure; thematic, but the implementation wasn't great. I think an infinitely-repeating area like in dungeon 3 would work well here; a pony training area with a nice long road whose end becomes its beginning (letting you walk in a straight line as long as you need to), and passive enemy groups off to the side, positioned so that they won't bother you if you're walking the line like a good pony, but you can fight them repeatedly for training and gear if you like. It might also help to have *some* pony gear just lying around in chests, to help get everyone fully equipped; there's a lot of items required across four characters, so every little bit helps.
Note that I didn't even run into the blinders/blindfold until I'd beaten the boss and sat down to grind out full pony gear, so I didn't get to experience the maze-like passages while impaired. Having missed that experience was probably for the best, I'd have found trying to explore while blindfolded rather annoying; it might be worthwhile to put in an item somewhere that removes eye-encumbering items from one person, in case anyone else is similarly bothered by the conflict between exploration and completionism.
