In the Journal to you can hear almost all of the unit's voice lines with their 3 voice actors, which is pretty useful for stuff you hear pretty often like Command D (voice line when you choose spell card and LW) or the skills, keyword Almost, for whatever reason the pre spell card and the actual spell card voice lines just aren't in the Journal, even though they're the ones you hear the most.
I don't think it'd be too hard to add (even for NN standards) and could be pretty neat to listen to them by themselves ("Welcome to Underworld~!" Is one of my favs)
