Lovely to see the announcement!
Tho as many people have said, just the lack of arguably the most interesting and deverse time of naval history, the time from 1890-1920, where so many different designs and ideas were tested and every ship basically looked completely different.
I mean it is very likely a huge pain in the butt to model of it but it is also very interesting to see. That's probably the biggest thing missing from the game...
And for the issue with the super battleships, they are decently cool and interesting what if concepts and building an 18" armed "light cruiser" is also an interesting what if scenario (also I am looking at HMS Incomparable)
I am just hoping they have a couple surprises up their sleeves regarding this!
I am cautiously excited for it, and finally a reason to spend more than 5min with the game because the of the lack of actual content that is worth while playing
