Seems like the Kongo has been tampered with. Worse dispersion and almost no Citadels for me in the Kongo now since this patch. May be its me of course but I don't think so. For example, I had a cruiser bow on chasing me at 2.4km and I never touched him in three rear volleys with all shots straddling and one twin narrowly missing. Previously I had put several shots in to him broadside on and it barely scratched him, and I'm talking fighting a Konigsberg here who torped me after a 5 minute chase by getting so close he could light a cigarette from my burning deck. Well played to him but I was furious that the Kongo was so inept.
Cough .. splutter ... dribble... give me my Kongo back!!!
