Lets say you lock a base, when inviting your battle pacts into a the fight, there should be an option to send a message that will be shown to all your battle pact partners rather than to have to officer comm them individually. Probably located below your list of battle treaties which would look similar to the alert box when alerting a planet or a player. Cost of energy would be 5 energy per battle pact that you currently have.

Possible messages would be: "Base description: level 3, 6800 shields, 1600 hull, 3050 attack, 2050 defense. Medium difficulty, taking it down on final hour." "Last hour on that base lock, let's make a push to take it down, shall we?", or "you guys ready for a base lock soon? The lock's on us." or "Good job everyone, base is down"

Ctrl+c makes o comms not a big deal.
If you don't want to do that though you can always set up a fb chat.

Eh, wasn't aware of that keystroke. And I'm sure quite a few people out there aren't aware of it either.
As for facebook, why not have something in-game that does the same thing more efficiently than what's already there? (individual o comm your pacts that is.)

This which can be done via fb vs game content?
Do I think this is a bad idea? No
Do I think (maybe hope) Dan has better things to write? Yea

Fair enough, It's more of a convenience thing than a new feature really.

do you know what works REALLY well... group chat on FB.. gather the leaders of the BP legions, in one chat and presto, everyone who is online, will (should) respond.
