The main reason I did not include is that the crafting system is the same with previous seasons more or less, and since I do a comparison of the changes, I found it to not make a difference.
That was changed in 7.2.5. Only the first seasons had destroyed keystones, and it was pretty easy to replace them (back then there was almost no way to not time a keystone).
My point is not that +10s are hard. My point is that it feels a downgrade to run +10s for a weekly instead of getting the myth track from lower dungeons.
I love 10s and how they feel. But they are challenging and a big ask for many players. The fact that those dungeons gatekeep the myth track vault will be a negative in the long run.
I feel that if it was more like previous season where we could get myth 1 out of +7 or +8 and max myth 2 form the vault would be best for the progression of the game.
