I have Try 1-5 hundred times, so my composition for always got S-Rank on boss node is = Slot 1 = CVL (any Torp / Bomb 3, 1 Saiun | x1 on Higest Slot Torp or bomber, x2 Type 3 Liaison, x1 Saiun) Slot 2 = BBV ( 4 Zuiun or x2 Type Ka Liaison, 2 best Zuiun) Slot 3 = DD (SONAR, DC, SONAR) Slot 4 = CL (SONAR, DC, SONAR)
About 1-4 is the "better" place than 2-1 for Complete Quest = [Bd4,Bw2] low HQ Exp, safest (if you got at least 3 SS). more CVL/CV to kill. About 1-1 The Quickest Place to Complete Quest = [Bw1] low HQ Exp, safest. About 1-6 the Quickest, Low HQ Exp & Safest to Complete Quest = [Bd8,Bw5] even Lv 1 Fodder Can Do that.
