I don't agree. We don't know the nature of his Nino, and he doesn't have Eirika so the best path to Nino Country is cut off. It's really not good advice to blow more than 22k feathers on a Nino if you don't know her nature. It could be -spd/+res for all we know, and then he's fucked.
Maybe I'm to blame for hyping up Nino too much but to be clear to everyone, Nino works best with a
very specific type of team composition. I went all in on her because I already had a 5* Eirika, a +spd/-res Nino, and was lucky enough to pull a Ninian on the latest banner. You can't just take any Nino and throw her onto any team and create a monster.
Look at this guy for example.
That guy? That guy should be using Nino, which is what I told him to do.
