+spd-def Olwen, +def-spd Morgan and +spd-atk Nanna

So im rly happy right now, building Olwen should be easy (depseration, SS2 and chaaaaaaaaarge) but my question is about Morgan and Nanna.

What should i do with them? QR +Fury on Morgan?

What about Nanna? Unfortunately with that bane i cant build her as i would do with Elise.
