the 'hype' ninja is kushimaru(needle guy), who is only a good choice if you are high power, jinpachi munashi(boomsword) is better in general

If you pull 400 seals in GNW its all about luck since some people pulled 400+ and got dupes before even getting the ninjas they want. Even friends of mine did the 300 pulls you need to get all the rewards from the rebate event and they didn't get the 1 ninja they need but dupes instead so its really your choice if you need a team right now or if you can wait and save more seals again and pulls again after your 400 seals in GNW. And depending on your power kushimaru might be overhyped since most of his damage is from just being high power vs lower power

So how does getting ay third raikage sounds with 2 rares from kage or gnw. I really cant evaluate his usefullness and strenght.

Are you in group with other high bp guys? Investing in GNW could give you edo sasori, who could buff all the edo deidara / kushimaru / edo hashirama in your field during gnw, which is awesome.

Also investing 400 seals in gnw could potentially reward you with a random kurama naruto in a few months.

Im top 10 on my server. And i just and think not many ppl use gnw ninjas in china... Is just a really hard decision to take. Can't ay be a safe bet and murder ppl?
