Well I'm one of the more than 10 that's using it, and I don't play SH5 and certainly won't be playing it for a good long while.
I probably haven't even scratched the surface yet in terms of what it can already do though so coming up with even more stuff for it to do is a tall order.
But I do like the idea of getting a little renown for sending officers off to take command of their own boats, that makes sense to me... after all if it's an officer who's come up under your tutelage it only seems right that his being found worthy of his own command would add to your own renown a bit.
