I've just tried it in GB. The funny thing is that, it performs well even against battleships. EOC 6" doesn't do 700 dmg/shell only around 350, and it doesn't have the range of a BB1 or a "pocket battleship" CA but it's still and outstanding gun for a DD1. Sometimes when the opponent didn't pay attention, I could do 10-15k damage and sank some battleships.
However the lack of displacement is a real issue. I couldn't load more than 1 bind of ammo and I have to use the DD1 (Light engine). Even with 3 men (lvl75) crew I needed to skeletonize all sailors so I had problems with the accuracy and the guideline length.
Maybe with some kind of lvl50-60 EVBE supervetted crew it would be a nice funship if you don't mind that you get really low XP.
