haven't touched the game yet (and still can't due to work in almost an hour), but from what i'm seeing, siegfried isn't worth the raging decrease buff (although i have seen a slight difference using it before so it can save you 1 turn to try and reduce raging and nothing more if you use abilities with it).

so yeah, she's only good for the stun nuke i guess... might have to run gilgamesh or arthur since I still don't have shingen or herc yet (so very close to herc being 90 points away).

and looking at a few other things, i could basically run nonsensei's team... only difference is that instead of dark ama (i don't have her), I can use nepthys or pharol, maybe even beelzebub
