Ah, yeah, I thought that would be obvious but looking at my post again the lack of context makes that list rather random, eheheh.
Hmm, so switching out will be sufficient for healing? I was initially concerned that it wouldn't be effective enough, but if it will work, that's a significant relief on the defensive side of things.
So even with Remilia spamming Curse of Vlad Tepes to buff herself, Meiling without buffs (besides a possible World-Shaking Military Rule) will be a superior tank? That's another good thing to know indeed, I had doubts that she'd be able to handle herself without buffs. I don't need to be concerned about that then, and Remilia can be an important attacker instead, though if I understand you correctly Curse of Vlad Tepes won't be enough to let her handle attacks in late postgame? That concerns me a little, but I think it won't be too problematic.
I had a feeling I was overlooking Youmu, but I'm not sure whether to go for offense or defense with Sakuya. Will she be better off as a damage dealer rather than a tank like I initially thought? I really thought Killing Doll would only be useful if she's buffed, but if it's still the most optimal way to use her, I'll definitely try to incorporate that into my strategy.
Hmm, I had considered the lack of magic but didn't see it as a problem...I haven't decided whether to just use Patchouli as another character to switch in for damage and switch out or try to raise her Mind stat to deal with magical attacks and keep her in. As for my other magical attackers (excluding Marisa since you already answered my question about her), I guess Yuyuko should simply be dealing damage with Saigyouji Flawless Nirvana, but I'm a little unsure about Utsuho, since she can debuff and buff herself. The self-buff seems bad due to the negative effects, but the debuff helps all of my magical attackers, and might be really nice for Yuyuko or Marisa to take advantage of. I guess it's better to build her for Magic either way though, since she's so fragile, it's really just trying to decide on how to use her.
Hmm, I see, so it isn't about the healing itself but the overheal? Hmm, I'm still not sure if that warrants adjusting my tanks around it or not, but I suppose it would be better to play specifically to a character's strengths and not worrying about maximizing Hourai Elixir, then, since it won't be worth it? A little uncertain about what to do with her now, but I suppose that's normal given that everyone says she's bad (and honestly, I've always thought she was rather subpar, but I'd like to use her anyway). Anyway, thank you for the input, it was very helpful!
@I have no name
Hmm, should I build Rinnosuke defensively then? I haven't determined the most efficient way to use World-Shaking Military Rule yet (It seems like there isn't really a hard rule for it in this kind of team anyway, since it's so lacking in buffs a single-time use buff with that kind of potency makes a huge difference depending on when it's used). I had actually given a lot of thought to Flandre before, but Youmu's superior defense would make her more useful for staying in to deal damage, yeah. Should I focus on attack with most of my level-up points and use the remainder for HP, or focus on her defense or another stat instead, or split it between those three? I can see her attack, HP, and defense are basically her most noteworthy stats (with attack being her primary appeal), so choosing between those three stats seems best, but if I focus too much on attack she'll be a tad too fragile, and too much on HP/defense will worsen her excellent damage, so figuring out a good balance between these stats seems to be the basic goal to aim for with her.
Overall, I guess this is what I'm looking at:
Marisa: Heavy/Complete emphasis on Magic for high powered Master Sparks.
Remilia: Heavy emphasis on Attack, maybe all level-up points into that stat?
Sakuya: Probably an Attack oriented build, if not a tank? Needs more consideration.
Patchouli: Undecided between splitting Magic and Mind or focusing on one of the two. Needs more consideration.
Meiling: Tank.
Youmu: HP/Attack/maybe Defense. Primarily physical damage dealer with some bulk.
Eirin: No idea, tank? She seems worthless for anything else.
Rin: So far nobody commented on her or Yuyuko, which I guess means nothing specific needs to be said about her? I'm certainly interested in seeing if Vengeful Cannibal Spirit's defense debuff is worth it or if Rin is yet another damage dealer in this party formation. I imagine she'd be pretty nice with World-Shaking Military Rule due to Blazing Wheel, too.
Flandre: Glass cannon. I don't see any other way to use her.
Yuyuko: Generic magical damage source, really.
Rinnosuke: Probably a tanky build?
Utsuho: Magic oriented build, all three of her moves look useful depending on the situation (besides maybe Giga Flare, what with that mind ignoring). Notably my only source of damage that ignores defense.
