How would Lyse come up with a really good battle strat? She doesn't know much in the way of those types of things. As a smart leader she left it in the hands of two people she knew could come up with one and who had not only connections, but respect. The poor girl is dealing with a friend's death and trying to figure out the best way to approach things because she knows said friend would have chided her for not having done so.

Minfillia on the other hand suffers from doing a lot of things off camera and for the most part having the shown useful bits having happened in 1.0. I doubt a lot of people would have liked it if before 2.5 we had a lot of cut scenes with her busy on a linkpearl giving the wol the "just one minute" gesture to the wol while the wol just stood there and listened to a one sided conversation about scout reports and what not.
