Something I feel that has always plagued this game is the uselessness of the announcement sent out by the developers. It's fantastic that you launched an expansion and you told us what vehicles are included... but what do they do? Why do we need them? At what level of station number do we need to worry about a new requirement? There is really not a single reason I can think of that members should constantly be left to figure it out on their own.
A page needs to be added to the FAQ with a list of what every vehicle actually does, when it is required, and etc.
