You guys seems to not understand that when this new op ninjas gets released it means you may start peicing them up so its not a bad Idea, If you planned better from the start, all your coupons and event resources must go all go to POWER. In every event you should check all the redeemables and plan what to go for. Missions mobilization, Luckyboard and Timelimited shop etc.. if you see charms, cave keys adv refines you must go for it, dont go for ninja fragments unless you really need that ninja and he/she must be usefull end game. All coupons you earn must go for power aswell use it to fill all your lacking resources when it comes to rebates.

All your seal scrolls must be used wisely, this is the only way you could get a ninja. If you played for atleast one year you are eligible to get one super rare from kage treasure or GNW treasure. I suggest you go for Kage since it gives usefull rares and if you get lucky to pull Ay you will be fine on 1v1 but if you get Sasuke he is also good. You will also get the rares and try to make do on what you have and make a team that works.

And the most important thing you have to stack one ninja, the ninja that does the damage, your carry ninja. We F2p's have a very limited resources and it takes us a very long time to be able to max out every power options on each ninja, so the best thing we can do is make a team that has one Carry ninja, the rest are supports. An example of a good carry ninja is Roshi, most of you would say go for watermain roshi poison cancer but unfortunately that doesnt work anymore on this era and what really works is pairing him with lightmain to get the lifesteal.

Lastly, you have to level freeze, reach 69-71 and you must hold that for long thats the only way you could get adv runes fast if you dont win your sage battles you will never get a lvl10 refined equipment. You must get atleast 1st or 2nd, 3rd is ok.
