I have to agree with Takosabi, the standard Matsuri should be replaced with arena Matsuri. Those were some very easy wins without the power differences and less time consuming. I didn't lose 1 battle & had to revive only 1 ninja.

Those who don't like the idea probably have 1 bad ninja in their team and focused more on power.

Well this matsuri is better but the rewards are worse. If they make rewards the same it's gonna be alright.
