The novelty of the cat ninjas, wears off REALLY fast...

My thoughts on the ninjas

Sasori [100 Puppets' Performance]: Sure why not
Minato [Fourth Hokage]: Eh, it's outclassed by even Jonin Minato, so I don't see why not.
Iruka: No thanks, you can just oh, I don't know, refine ninja frags for him.
Hanabi: Would make Fireworks useless that week.
Gaara [Suit]: HA, good joke m8.
Hinata [Cloak]: Trust me, you don't want her in fireworks, she isn't going to be used in serious play.
Kakashi [Susano'o]: I could see it, he isn't that good, but still useful to majority of players who don't have him.
Hidan [Death Possession Blood]: Eh
Naruto [Chinese Style]: No thanks
Tsunade [Taisho Period]: Quite the reach on that one
Konan [Taisho Period]: Pretty sure this ninja was in fireworks already.
Tsunade [Fifth Hokage]: HAHAHAHAHAHAHAHA, wait you're serious? Let me laugh even harder. BAHAHAHAHAHAHAHAHAHAHAHAHA
Masked Man: Eh,
Madara [Five Kage Summit]: People been asking this for awhile and Oasis won't deliver.
Itachi [Anbu]: Just to get people to shut up about him.
Hanzo Salamander: Honestly, the value of this ninja is too low in my opinion to be in this event.
Danzo Shimura [Danzo's Izanagi]: Pretty likely since no one will use him.
Utakata [Edo Tensei]: Most likely won't since it has its own treasure.
