Yes, the PTS is testing legendary perks later today! I've been looking forward to that feature for a long time.
I wonder, since the PTS is now open to all PC players, is the NDA lifted? Does the P finally stand for Public now?
Correct, we're removing the need to sign a Non-Disclosure Agreement for the Update 20 PTS.
However, since there will be people who aren't going to play test in the PTS, and some who dislike learning about new content before they can experience it themselves, we're also going to request that PTS players use spoiler tags or inform others of potential spoilers when discussing upcoming content outside of the PTS forum.
We're also asking that the majority of bug reports and feedback for PTS content be shared in that PTS forum. This is because it's much easier to sort and read through everything you all are sharing with us when it's mostly located in one place.
You didn't ask about most of what I wrote, but I'm hoping it will be helpful to others reading this thread too!
