One of my favorite little additions in patch 2.3 was the boat/zeppelin vendors. Sure, there's a whole crew there, but after talking to them once to see what gossip they had, the vendors were the only ones I went back to. Since Blizzard refuses to take me up on my suggestion to allow fishing from moving boats, it gives me the one more thing to do while waiting for that zone-in screen, aside from chatting and making bandages. Being able to sell trash, stock up on reagents, and sometimes repair during this downtime is really nice.
Unfortunately, the boat vendors have been disabled in a hotfix to the live realms, for vague reasons. Nethaera clarifies that there are "propulsion issues" that necessitate the vendors being out for the time being, but that they'll be "back on duty" as soon as the issues are fixed. Possibly related is a note that the entire boat crew is gone on the 2.3.2 PTR, "for testing purposes." Hopefully the vendors will be back soon; until then, my boat rides will be (even more) boring.
