There are some things I am definitely looking forward too in the 5.2 patch but there is a lot I dread at the same time it looks as if we could take a pretty good hit possibly. Have you looked at any numbers from the PTR yet?
Not needing a glyph for the 4 shard is going to be nice and allows us another glyph spot. I am also excited to get the new version of dark intent. The changes to sacrifice worries me some because if your someone like me or one of the others that are having issues already 5% is going to be tough to swallow.
