What I find most arcade is the sheer numerous encounters with huge task forces consisting of at least 2 BBs and tons of escorting cruisers and destroyers. That's pretty much non-historical, as, apart from a few occassions, the battleships of the Imperial Japanese Navy pretty much were kept in reserve at home. That and the large number of Carriers I've run into..
Of course, that could all be just coincidental in my patrol record, sort of being in the perfect spots all the time, but it gets pretty arcady when I bag at least a BB every patrol. At that rate, the Japanese will run out of capital ships by the end of 1942... oh wait, they don't -the ships even respawn in harbor (A Kongo did this on me - sank it off Hiroshima, went on to see what went on in Kure, and found another Kongo in the exact same spot in Hiroshima upon returning there. Plus of course I sank quite a lot of Hiryu class CVs - there seems simply no point in sinking capital ships. In SH3 at least, they were so rare that I considered it quite an achievement even finding one.
But I guess all this will be rectified soon by one or another mod
