Valid point, of course. Getting the 3* is nice, but I wonder if it's feasible to reach 7* via the event missions?
Definitely a nice addition to find a way to get them, though. Wonder how long that'll be around before it rotates out.

Of course it had to be the 3* I had the least interest in, eh? :^)
I wonder if Isabelle will have another way to obtain her eventually.
