Simple change, add a Guild Airship door in House Cannith. Cannith is the only enclave you cant navigate to and from via airship, for no good reason. Its also the most conveniently-arranged enclave, with an outdoor tavern, bank, trainers, auctioneer, mail, and crafting hall all close to each other.
Likewise, you cant Teleport to Cannith, but you can Teleport to two locations in Kundarak. Change the Kundarak Crafting House teleport to Cannith Crafting House.
Lastly, add your Airship to lists of places you can Teleport. Its often the first place you want to go on your way to other destinations, so why have to go through the extra step of teleporting to Kundarak Bank and then jumping down to the Airship port? It diminishes the value of Teleport itself, if you cant Teleport direct to the Airship, and the Airship offers you many of the same destinations as Teleport anyway.
Big improvement for everyone. Easy win.
A slightly less simple request...add an option for Guilds of a certain level to sell an exclusive clicky that lets you teleport to your Airship once every, say, 30 mins. It'd promote the utility of guilds in general if the Airship was more accessible to all members. It'd provide a way for guildies to gather together more quickly, and then proceed to whatever content they want to do together.
