Sword Wielding Dancer Number 4

The Dancer class uses swords. There are a few refreshers who weren't "dancers":
Bards in Jugdral used magic.
The herons from Tellius were beast units.
And of course Azura is a singer and uses a lance.

But I don't know of any who used bows. So if we get one it will probably be seasonal like dagger Olivia.

In the gba games nils and ninian can't attack at all, even tho they were manaketes, and both fe6 and 8 have sword dancers, so yeah
