For some, the boosters were a scratching ticket with "no win". I got a refund myself that I just invested in Mega Santas = ended up with 4-6 ships instead, 2x 180 days premium and bunch of other things.
For a working man like me, the directives were clearly unrealistic with me having an approx of 4 hours a day to play, but I was able to grind Gorizia for myself last night (though it was a 10 hour long stretch to complete the few last directives.) I also heard that people that were really able to play a lot were able to get the ship with min. amount of doubloons, yet heavy commitment.
Conclusion: I don't think the event was bad, I just think the hidden extra ship fee behind the boosters was a bit shady. It would have been better, that with financial aid you could have been able to get the ship with buying the 3 boosters and perhaps clearing the first 3 directives. On the other hand, I just laugh at people complaining that it's a 200€ ship as an investment, it's not. However, I will still be supporting the game as usual, won't be going on this full-on "I'm quitting and never coming back because I got caught up in a capitalistic charade."
Just hoping that the next event is laid out better for us, reveal what's hidden behind those freemium doors, before we invest in the ones to begin with.
