I installed the PTR client yesterday, and today I spent a few minutes getting demonic essences and making some of the new crafts. Nearly every one of them was pretty decent. Anyway, I also did a little bit of PvP, and it was interesting. If anyone would like to try it out, get the PTR and send me a friend request.
