Yes, the new airships are nice.
Yes, the new amenities are nice.
The expansive, empty top deck is not nice.
At least give the option of navigator/plane shifter/whatever the new equivalent might be to be placed near the captain.
I also personally would like the option of bank/tavern/mail/AH/repairs on the top deck.
It would just be so much faster for quick sell/repairs between quests to have these on the same deck where you load in instead of having to go through another loading screen, and guest invites to the ship will not need to wander around trying to figure out where they need to depart.
edit: After placing further buffs, we find the captain can farshift. So nevermind. But other things on top would still be nice.
