Basically, 5-10 FCs that can ally and converse in an overarching Alliance channel. FC leaders would just need an invite/leave/join menu. Not thinking much is needed. This would allow friends of various FCs (but also new ones) to communicate and organize ventures that are otherwise a little hard to queue for sometimes (certain 8 and 24 player queues, pvp) as well as other events.
Sitting by the fire trying to queue for Void Ark wondering why we don't have this. Would be fantastic when things are slower in your social network, not to mention giving a larger scope of the game.
I really want this!
