Just a brief update to this.
I've being tooling about on the 1.3 PTS (got my main copied over), and so far, it's looking pretty cool. The Group Finder is nice, providing top end comms as rewards for random Hard Modes. It's not cross server either, so you don't have the cloak of anonymity that most nubs hide behind, which is nice.
Augment changes are nice too, adding Augmentation Kits which allows you to add augment slots to any piece of existing gear. It means you can make that favourite custom set of gear even more viable at end game.
