[REQ] Escort types in campaign

[AntEater]

Sofar I, all the convoys I ran into were mostly escorted by fleet destroyers.
Especially stupid were the huge numbers of Akizuki class AA destroyers.
While this is certainly one of the most beautiful warships ever build, Akizukis and other fleet destroyers were high value ships and were mostly escorting fleet units or really high value convoys. They should be rarer.
In 1944, some older regular fleet destroyers (early Fubukis and Shiratsuyus) should escort convoys, but the vast majority of late war convoy escorts should be subchasers, minesweepers, minelayers (do they have DCs in SH4?) and old destroyers.
In mid- early war, older destroyers and minesweepers, but no fleet destroyers at all, except for troop convoys for landing operations like Guadalcanal or so.
The hordes of Akizukis (I sank 4 in 2 war patrols on USS Mudskipper) are boring.
Sh4 has so many ship types, yet the campaign does seem to use only half of them.
