Might come a bit late, also just my opinion, so don't kill me x.x
Donation Points? I agree with previous statements, people would just transfer them off and back. Even if this was somehow repelled, I don't think it would really take that long to gain them back. At most, only the DP that you received through giving real money should stay.
Curse Seal/Seven Star Tattoo? They should go. The only thing they take really is time, and some witt with the Enhanced tattoo. They are both supposed to require work to get them, I recall?
Money and Gems? Erm...nobody should even doubt this one. If you had trouble saving for something then if you start over it ought to be much easier with your already existing knowledge.
Dwellings? Gone. They can be built again, only takes time and effort, just like in real life. Keys? Those can be given again.
Mounts? Gone. They aren't very expensive in the long run, and they will soon be changed anyways.
Companions? Gone. They reset after you kill Orochimaru anyway, and aren't that costly in the first place.
Spouses and flirt status? I suppose these could stay, if thinking roleplay wise.
Hidden Stone Village access? The description says, only the most powerful can get there. Wouldn't be very precise if academy students could get there, no?
Name change? That has been discussed already. 10 000 DP, if you can't pick yourself a name you will like when you create your character.
Rasengan? Should go. If you already have achieved it, then you know what to do already, thus you should get back to your former status quicker.
Did I miss anything? x.x;
Either way, I'm going to reset no matter what we will lose. I already enjoy the forest fighting system as it is, and this is going to make it even better
As for roleplaying, that I'll probably keep it as it is. It'd be a tad too weird for my character to just suddenly be reborn as an acad o.0;;
