Good units to have for these roles are Ciara (She nukes well, but doesn't provide all that much.), Stein (Very useful mitigator, upgraded Krantz.), Elza (Does essentially everything except mitigation.), Melord has a little bit of several of those things, Rengaku(Very useful for late-game content), Lara(Pretty much everything you need), Felice (Best BB fill in game), or Sirius (He's a good unit all around.) Elimo and Zenia omnis are coming, but Zenia is a gamble overall.
