So I've noticed that for some reason many cities have world tour but El Nath doesn't have one. This can be really annoying because if you want to do shaolin boss for example you'd have to walk all the way back to orbis every time. Maybe put a world tour NPC there too? I'd suggest putting a world tour NPC in CBD too, I mean CBD is already part of world tour so why wouldn't it have an NPC there? Also maybe get rid of that plane and just let Spigel take you there instead just like shrine/lushan town?
Two wise individuals have shared good knowledge above. I will just add that from CBD you can quickly walk to Boat Quay Town.
