The goblet desperately needs more "lushness". This is supposed to be an oasis in the desert.

1)We need more water on the higher levels of the zone. Not just the center.
2) We need more green lushness. Tall palms and shade trees in the planters and not just short bushes and cactii.
3) We need more colorful house models. Every house is 90% (or more) the same drab sand stone brown color. The only thing we can do is accent it. The real reason the Mist and the Lavender Beds are more popular is that they both have a vastly superior color pallet.
4) We need better lighting. Even during a clear day, lots of areas in the Goblet are full of shade. When combined with the drab colorless surroundings it makes the zone feel depressing.

5) Give us actual access to the buildings/airship dock. The zone could have a clear advantage if things that are there were opened up for actual use.

6) More NPCs!

7) More holiday/seasonal decorations!
