I use these events to buy warbond CCU's to plug into my 'current' fleet plans.
It is basically a bunch of warbond CCU's so the ships are not 'exactly' sitting in my hangar. If the game were to go live, I could generate all the ships. Of course, I'm waiting to add more warbond CCU's to the fleet as my current SC game is to lower each ship's melt value as much as possible. Weird ... I know.
I have all medical ships, minus the Cutlass Red. I ultimately figure FPS and Medical are my primary careers.
I have combat as I think that will be a big part of the game: Javelin, Polaris, Perseus, Legionnaire, F8C and Scorpius. I don't think I'd have the Javelin if I wasn't part of TEST.
I have the Terrapin and Odyssey as my exploration ships. I could easily have the odyssey become a 600iX or Carrack as those ships are part of that CCU chain.
The Omega and Raven are ... just because. The C1 is slated to be my daily driver.
A few ships not on the list, but in the hangar are: Gladius for 'training'. Orion and BMM for resale or renting in-game if needed to generate UEC.
