Also what time does it release PST? I live in Taiwan and can really only grasp the time conversion there.
With Weakauras, you can either put in the time & learn, import other peoples auras (MMO Champion has several threads dedicated to it), or use something else if neither of those are something you fancy doing.
I've always used Grid. Honestly, all the healing addons are so flexible that you just need to find something you like the look of & spend the time setting it up right.
No idea when the US launch is.
