So I got my Legacy after finishing act 1 of my consular and now Im gain legacy exp but besides the coming soon, I have no idea what it going to happen, besides saying I get legacy powers and extra CC feature, I would like to know if anybody know something of it?

I earned level 2 legacy, but there is currently no reward for it. It simply says that my legacy progress is being tracked and when the rewards are added to the game I'll receive them. So you know about as much as anyone I reckon.
