Timewalking Content Will Scale Up To Player Level in Patch 11.0.5 - No More Timewalking Gear Minmaxing

wowhead.com:

A minor change recently announced in Patch 11.0.5 will drastically change how Timewalking Dungeons work. Dungeons will scale to the player's level instead of the player being scaled down to the dungeon's level.

This change is being made to help Blizzard maintain balance and the intended tuning of Timewalking dungeons, but it has a very sad side effect on a niche activity: Minmaxing gear for Timewalking content.

• Timewalking dungeons will now scale enemies to your current level as opposed to scaling you to the level of the dungeon.
  
  Developer’s note: Timewalking now uses the same scaling system as Chromie Time, allowing us to better maintain Timewalking dungeons and control their intended tuning.

But What Does This Mean?

This effectively transforms Timewalking dungeons to follow Chromie Time rules, by adding dynamic scaling to enemies. Level 30 players will be facing level 30 mobs, and Level 80 players will be facing level 80 mobs. This scaling was already seen during Remix: Mists of Pandaria, with hilarious side effects.

Previously, Timewalking dungeons followed a different scaling rule, with the players instead being scaled down to the level of the dungeon. This meant any items, enchants and gems that player has equipped are also scaled down. This rule has a niche, but fun side effect: Items from past expansions become useful again. Some of these power gains include:

• Effects from crafted gear of the past, including old enchants and gems;
• Azerite Gear and Traits from Battle for Azeroth;
• Gear with guaranteed multiple sockets from Mists of Pandaria and even further in the past;
• Items with powerful effects of the past such as old Legendaries and Trinkets.

This created a niche but very involved community that looked into min-maxing as much of their gear as possible to maximize their effectiveness in Timewalking content.

Timewalking gearing became more mainstream with the introduction the Timewalking version of the Mage Tower near
