Fleet experience requirements?

[Will]

But don't PDC-only ships start to run away, because they have "no weapons"? The shield-depleter scheme fixes that, but it adds some extra cost to the venture.

And I think that in a simultaneous game, you could end up having 30 combats (one a 'day') if you have the the fleet already in position. It's been a while since I've played, but I do remember a few cases where there were 30 combats in a single sector in a single turn.

And don't forget, instead of giving a fire&destroy, your enemy could also gift the ships back, or even better, to a third party, possibly someone you're allied with.
