Smart Choice for Brave Axe+?

Cherche is a much better brave axe user compared to Camilla by virtue of her ridiculous atk stat (8 higher than Camilla at lvl 40, which effectively becomes +16 considering brave axe). I think going for a different bane like -res or -spd is better in the long run since she actually has a pretty good def, but it's the current one is still a good choice if you're f2p

Cherche for flyer emblem or Frederick for cavalry emblem
