Fleet Mega Pack

I know you're asking about the Mega-Pack, but when I first started working on my ships I bought maybe 8 of the Fleet Data Cards for 499 crystals each, and I actually felt they were worth it. It's possible I just got very lucky though. I think only one of them was the 10 shard minimum, but I did get several in the 40-65 shard range, maybe even more on one, and then a few in the 15-25 range. I was able to immediately unlock Five's ship and get it to 4 stars, and Ahsoka's ship was bumped up to 5 stars. I stopped while I was ahead though, because the last couple were for ships I never planned on using.

I would say if you're just starting out on ships and you're not just trying to get shards for a few specific ships, then it's worth getting some. Then you can keep working on the ships you got shards for and use it as a head start.

The Mega-Pack does not seem worth it at all to me, and that's been verified by many who have purchased it. Definitely better to get character shards from elsewhere, and also better to get ship shards from the 499 pack or from farming.
