I actually have been thinking for a while that Guild Airships would make alot of sense. In GW1 you could access guild hall from anywhere. Having access to an airship from anywhere makes more sense since it travels. Maybe charge a set 1s teleport fee for “fuel” and have it only teleport you back to previous location, like the HoM orb. Gives a benefit to having a guild when you are in places like arah and dont want to spend over 3s to go to LA for crafting and forge. Can have its own section under upgrades, or simply give it the section Architecture, which makes sense since it would be building on the ship, and guild bank doesn’t need its own seperate section.
