AOZ tier 10 not the same as old tier 1 as blizz states

[MageCraft-1617]

@PezRadar

We’ve restructured the earlier tiers of Abattoir of Zir, and the experience now begins with a difficulty close to that of Tier 90 Nightmare Dungeons. The Monsters continue to rapidly scale, reaching a similar difficulty of Nightmare Dungeon Tier 100 by Tier 5, and matching the current Live difficulty tuning by Tier 10. Additionally, we’ve reduced incoming damage by up to ~20% throughout all Tiers of Abattoir of Zir.

Tier 10 is unchanged.
Where did you see “Tier 10 is now what Tier 1 was”?

Tier 1 - similar to a level 90 NMD
Tier 5 - similar to a level 100 NMD(->OLD Tier 1 AoZ<-)
Tier 10 - 6…7…8…9 ramps back up to original Tier 10.(UnChanged)
Incoming Damage was reduced by 20%.

At least that’s how it reads to me.
