10.2 Mythic+ Testing is now available on PTR and here are some changes to Waycrest Manor and Atal'Dazar. Atal'Dazar snaps still work but are harder to pull off.
All doors in Waycrest Manor are now open, allowing you to choose the exact path that you want to take!
Anyone who played Atal'Dazar in Battle for Azeroth remembers how much snapping you did in this dungeon due to how deadly it was. While snapping still works, it's a little slower and causes the mobs to evade for a short period of time before snapping making it slower than before. Unfortunately, the mobs still seem as deadly as before so it's something that you'll probably want to continue doing in current state.
With all the following snaps, if the mobs can reach you and melee you, they won't snap and instead walk to you. However, if you stand on a spot where they can't melee you, they will then snap after a short time.
Here's the edge snap with Saurids.
There's also the spawn snap which is much harder to pull off since it's easier to reach you at the spawn.
And lastly the side snap outside of each fence.
Originally, the trash directly out of Vol'kaal was so overtuned that the common strategy even in pugs was to skip it. It was so common to skip that back in the day, we made a massive post going through all the ways to skip it. This was mostly due to the double Reanimated Honor Guard.
In BFA Season 3, Blizzard tried so hard to get people to play this pack that they made it harder with a True Sight Void Emissary in the middle of it which did nothing but actually make it a requirement to skip this pack because of it's difficulty. It seems Blizzard has learned and removed one of the Reanimated Honor Guards leaving
