The moogle tomestone events are honestly just one big grind.
I had a couple in my FC who were still in HW in the last one where the BF insisted on just farming everything before continuing msq, while the gf wanted to continue MSQ after farming the most important items. I've heard several other people mention how they just feel like they have to grind it out, even if it isn't fun just because they'd feel like they're missing out. (kinda like the pvp pass, but that's not relevant here)
So here's my suggestion for future Moogle Tomestone events.
Make it similar to khloe books, minus rerolls & second chance points. Have the moogle hand out a book once a week. can be a 4x4 or 5x5 grid. On it are the duties that are included in the event. (make these duties the same for everyone, so people can easily organize. this is a big flaw with the khloe book)
If you get a line woo you get a flat bonus of extra tomes! complete the whole book? even bigger bonus.
This would gamify the event, make it feel more interactive. It would turn it from a mindless grind to a more varied and weekly experience.
Of course people who want to just mindlessly grind, still should be able too.
PS: bring back the MGP option too. It's the only repeatable thing that long time players can get.
PPS: Wasnt sure where to put this, i'm hoping it'll find its place.
