Too many high level missions in event store and no room to get and keep. Super expensive if they appear in store later. You can't switch officers around while on the ship you have to go back to base; and you can't swap ships while another is being repaired. You have to wait to get back out. So you really don't ever need more of the same type of ships than you can use. 2 until level 17. I was able to get my account reconnected after phone issues.
