So, if the Italians took the wrong idea from Lissa then all their ships must HAVE rams!
Always possible, but then there
is a lot of effective ramming in DW 2.5. Some ships are very good at it in fact.
I think it was rather faction specific. As a Prussian player, my escorts and frigates were some bread and butter units for me. Other factions, they were somewhat more disposable. However, overall the design of DW 1-2.5 favoured small ship types, which is probably one of the reasons the fleet comp rules put a limit on them.
Oh indeed. Some faction's escorts are very useful, such as the Korsors for the Danish (A decent gun plus a one-shot mine dispenser), or the Fury for the Black Wolf (With its ability to deliver Devastating Munitions as a group)
Escorts are meant as a level of extra protection and firepower for the vessel they are escorting, is my take on the class, and DW 2.0 and higher
really expresses that well; Destroyers are a more flexible option which is as it should be.
