I've gotten him, and i run a team with hashirama NY and 3 high chase ninja and I have to say that hashirama NY is definitely S tier support in my opinion. The extra chase is helpful no matter which of the 3 ninjas get it, and as you have stated, his skill and immunity+tankiness is very neat.

I would suggest getting kakuzu 4 stared and BT, then you can run kisame+kakuku+hashirama NY+fire/water main for that sweet full chase team. I would then put kakuzu pos1, hashirama pos2. Best use is to have kakuzu auto once first if enemy has dodge, then hashirama ninjas like edo minato. Then you can easily win unless they can still clear the debuff.

The way I see it, fuku isn't about getting a ninja for 25k coupons.

You are buying 25k coupons worth of things from other events, be it ninjas or BP increase, and then receiving the fuku benefits as an added bonus. The question isn't if the ninja is worth the 25k, the question should be is the contents of all the 25k fuku rewards combined worth it to you? And is the fuku ninja worth it/viable for YOU?

Because in the end of the day everyone has different opinions about ninjas and everyone has different teams/ninjas so it will vary between everyone.

I have been very happy with my hashirama NY, he has allowed me to beat kushina/edo minato teams a lot easier than before. I've gotten so6p in the arena a lot easier with him.

I don't see any baiting, just straight out facts on what you get for 25k coupons fuku deal.
