Ok I'm not saying that GNW Shino is the best sign-in ninja, but he's not that bad. Everyone's out here trying to claim he's the worst thing since Ebola and he's not even the worst GNW ninja (see Neji, Choji).

Yes, Kiba makes more sense since he was a super early monthly freebie. Obviously people want to see GNW Sakura, but there's no guarantee she will come on any given month, and any comments regarding if/when she will be a sign-in ninja is pure speculation. At the end of the day, giving GNW Shino versus another ninja isn't the game altering event some people are making it out to be.

Anyhow, there's literally zero that can be done about it right now. No matter how much people complain, GNW Shino is going to be the sign-in ninja for May.

Hey

As @Leumas stated.
It's not the worst thing and frankly, it's much better than some GNW Ninjas.

Now please understand with the release of the Edo Treasure, we'll have newer options to include.
From GNW Hinata, GNW Temari, etc. It's something I'll personally relay to the team. And of course the desire for GNW Sakura as well for players.

And in my personal opinion, GNW Shino (Nonfarmable Character) is nowhere near as bad as Jiraiya.
But if course, everyone holds different value and I completely respect yours.

Thank you for your opinion!
