Advisor API Changes

So I've started updating my advisor code and checking to see what's changed with the advisor endpoints. This is part a refresher for developers using these endpoints and haven't really checked for changes in a while and also to make some observations of what's still missing from the endpoints (private and/or public). For raids which are still exclusive to the private endpoint, there's now a "difficultyIdentifier" variable present on raid tiers allowing you to dynamically check between normal and hard mode. My legacy code pulls the challenge skulls for King's Fall, but I assume given what's happening with Nightfall data, that there will eventually be a skullIndexes variable for filtering which challenge skull is active for that week (if that's how they will work). The weekly Nightfall tiers now have a "skullIndexes" array that you can use to filter the skulls available on the playlist activity for the week. Sadly no Heroic variant yet, though I believe it has always been "Fresh Troops" every week so far. Is is supposed to be locked or change each week? There doesn't appear to be a way to identify which strike the Nightfall is, which is the same in-game where you won't know what strike you will get until you go in for the first time despite it being a set thing for the whole week. I assume there's some kind of technical issue given it's using the same playlist activity type as Heroic which is always random (though clearly not random enough that I don't do each strike twice in a row multiple times -_-) that makes it hard to provide a way to expose which strike is the set Nightfall for the week? For Heroics, the numberOfCompletions (out of 3) isn't getting exposed yet but this information is present on the weekly Crucible. I know the Arm's Day data has been there since 2.0, I just haven't touched it yet, but it's good to see it there. If anyone knows of any other changes to these endpoints that haven't been brought up yet, feel free to post them up.
