I have to so say i like to agree with Pavja's2 idea.
Just cause its meant not to be easy to get a airship.
Specially as Non doner. (Which is already a huge upgrade from not being able to have one mind you)
it will also involve teamplay when you get one seeing how expensive it is. And thus creating more of a community.
A ship should also not be seen as "Just a way to do something" Its an Exclusive way to do something. and that also means not everybody is about to get it. Specially not newcomers
