Great question Crash! I checked with the devs and I would recommend holding your lockout. I have no confirmed release yet but we are trying our best to get it out ASAP, like Jeff said, this week! Hopefully I will have more information on the 2.2 release very soon.
To reiterate, if you want to hit NM TFB this week I would recommend holding your lockout. I will update as soon as I can, especially if that changes!
Not sure if you will reply, and I'm sure there are a dozen threads with this question. But Why isn't Nightmare mode on a seperate lockout? Especially if it includes a new tier of gear?
Thanks in advance for any reply
EDIT: I see that was asked two posts above mine lol i will keep my question here though
