fleets

I'm still having a hard time grasping the concept and controls of a fleet.
Does fleet allows you send multiple ships in one shot? And how to do it correctly?

There is a tutorial. The do move in a group. But I am not sure if they defend and attack as a single entity. Anyone?

They will defend and attack as a single unit. If you look at the fleets atk values and def values it should be listed.

You should be able to use ability commands from a fleet as well, but currently there is a minor issue with the commands that will be fixed in the next client.

Strange. In the Fleet window neither ATK or DEF is added.
