I understand that thanks to the people that have donated to the game, it is better, but aren't you happy with the donation points and kyuubi days you get each time you donate to the game? for me that is enough, even an Academy student with a Kyuubi is able to kill the dragon in one game day if they know how to use their forest fights along with Kyuubi.
I think that Kekkei genkai should remain at it is now, the game would be very boring if you could get a kekkei genkai reset each time you donate... let's say 35-40$
What would be the point of doing forest fights and ranking up in the game if you can get, the resets, for me, something you have to work hard to get it, by just donating some money?
Then people would start demanding dragon kills instead of a KG reset, like I don't want the kekkei genkai or the kyuubi, but I want the 80 dks... it would be troublesome.
