For specific map (1-5 & SS Boss event), i still hardly recomend using 3-5 DD & 1-2 CL ASW stat because ASW capped at 100 and enabling OASW, unless upgraded Sonar / DC math surpassing cap damage that i don't know. 4-3 still reasonable for early train, but unupgraded Sonar / DC is enough in my opinion.

Unless you guys didn't need other primary equipment to be upgrade, i won't say more than this @_@
