i dont recommend for you to jump into a new server because it is a total waste. you have reached lv 75 and power that is not a small milestone, if your start again that mistake over mistake. you can fix it at your current server plus saving resources is even better and faster than at new server.

To-do:

-buy naruto6p or sasuke susano

-PURIFYING first then REFINNING then CAVE EXPLORING then NINJA ASSIST then TREASURE TOOL and so on systems.

-save coupon for Fukumaru deal, great plate,sakura freindliness events

-if you dont have good support ninja make water main your support, she is best support early game. kurenai full breakthrough is one of best support.

someone will tell some more idea.
