So I'm making my KM team... what roles do I need to fulfill? I just got Sirius to 150 but haven't maxed out his SP yet (though I can probably spend a few days doing that if it increases the chances). I've got quite a few OE but no Azurai or Juno.
PREFACE: Gonna leave this here, but I realized midway though that it's rambling and not coherent. Going on 40 hours of no sleep on account of family shit.
Defense and BB management are the crucial details to have hammered out, otherwise you run the risk of getting blown up every third turn or on some threshold. Be sure to have stronger element null on any dark unit, prioritize hp and defense over attack. Two-turn mitigation is really nice, but honestly I mitigated every turn and made sure to have tri-stats (I had to use Atro) and conversions (Lara) active all the time. Krantz is super useful, because his bb fills like crazy with his sphere, he heals, and he adds dark element.
I only used one nuke unit - EnsaTaya - and she laid it down, even with defensive spheres (and element null). iirc you have both sirius and Ensa, so what I suggest kinda depeneds on whether you have Felice or not. If you do, I'd suggest using her as a leader to ameliorate what is otherwise gonna be an annoying trial for managing gauge, then deciding whether you wanna use Ensa or Sirius. I found there was minimal overlap between ET, Felice and Atro, and together they covered all BB-related bases.
Don't know as much about Sirius, but if you have him and don't have Felice, I think he'd be a really good lead, provided you bring gauge-fill when attacked and OD fill in some other form.
My team was Felice (lead), Ensa, Atro, Lara, Krantz.
