Sending teams out to Expeditions lowers their Fatigue slightly. People suspect that the probability of getting a Great Success might depend on how high the fatigue of your team is overall when you send them out (e.g. Sakura fubuki swords will give you a higher chance of getting a Great Success). That's unconfirmed though.

The other "negative" effect is that it's marked down in your Battle Records.
