Warcraft: Ships, Shippie Ship Ship

My days sailing on the high seas are done for the time being as I have obtained the Draenic Sea Chart without any failures. I don’t intend to send my ships out on any more missions unless I really need to, and I don’t see why I would need to. Seriously, is there no other reason for the shipyard than this one bit of legendary quest chain? Seems weird to me. Perhaps I will need it again for the next part, but I still need to collect those Tombs of Chaos before we get any further. I only raid LFR it’ll likely be slow going as currently only the first wing is open, though the second wing should open tomorrow.
