What is the ruling on the ability to drop upgrades from your ship and destroy them instead of saving them? IE you would be able to remove an upgrade from a ship and not have it count against your fleet total.

In the FAQ... it talks about saved (none equiped ones) counting against points limits... it also says you are free to 'bin' your ships... so I'd say you are free to bin the upgrades (you dont recoup any costs though :p)

Q: Can a player voluntarily remove ships or squadrons from his fleet to reduce his fleet-point value? A: Yes. However, ships or squadrons removed in this manner are treated as destroyed. The player does not recover resource points from their fleet-point value. Cards with unique names (such as title upgrade cards) that have been eliminated in this way cannot be purchased again by any player during the campaign.

Q: Do upgrades that are not equipped and are set aside count as part of that fleet’s total value? A: All purchased upgrades count toward the fleet’s total value, whether they are equipped or unequipped.

According to the FAQ, you are only allowed to get rid of ships and squadrons - not upgrade cards. The exception being Title cards, which are non-transferrable.

Being a casual campaign, you can always house-rule otherwise.
