hi there.
just thought i might comment on it, please take everything with a pinch of salt, as i am quite unexperienced myself.
but i think your habit of piling hsips into naval battles is actually detrimental to your war efforts. you will gain the naval equivalent of stacking penalty above a certain number of ships (i think its about 12 generally, depending on the fleet composition though)
you can see that in ongoing battles. besides the generals picture there is a percentage number (positioning its called for navies). yours often is lower than the brits. even though you win and sink stuff, i think you would do just as well with fewer ships and take less org hits in the process.
just htought i would point that out, in the hope it might help you out a bit or be corrected by someone who knows what he is doing in case i am wrong
