I have a suggestion where I think it would shorten teleportation times when doing Guild Base Quests. My idea is to be able to teleport anywhere from the guild base. For example, say one person takes a quest from "Construction Manager" and needs to go to "Gloomy Forest" I suggest having that option from the teleportation crystal along with all the other places one would need to go. (i.e.: Sea of Oblivion, Lunagrant Woodlands, Gloomy Forest, Hazed Wilderness, Sleeping Jungle, Nightfall Citadel.)
I believe this would shorten the load times for doing quests and going where one would need to go.
Thanks for reading/looking.
