Yeah I did some reading and apparently it's way quicker to level after you beat Xemnas as well (which I haven't done yet).
There's a ton of bonus content for the post game. You get the Data Org. fights where they all have tons of health and new strategies, the Paradox cups in Olympus, and the Lingering Will superboss.
I had to grind to 99 and synth some of the best equipment to stand a chance.
EDIT: So do you think we'll see any gameplay changes in 3DHD? They changed stuff up for 1.5 to smooth out some of the rougher parts of KH1, so it's not an impossibility.
At the least, I'm hoping for:
- Slow the Drop Gauge, and turn it off during boss battles.
- Remove the minigames and make Dream Eaters level up super quickly so you don't have to grind for so long just to get good skills. The way I see it, if you use a Dream Eater for an entire world, you should get all their skills.
- Make fusing new Dream Eaters easier.
- Recolour the Dream Eaters so they don't look terrible.
