Due to a bug introduced with the War Within pre-patch, some players are receiving item level 250 gear from the weekly cache.
We've seen numerous reports on Reddit and the official forums that the Last Hurrah weekly quest on live servers drop low-level gear for some players. Apparently, the bug was first introduced with the War Within pre-patch two weeks ago and still hasn't been fixed.
Here's an example of a low item level drop from the Cache of Awakened Treasures by Omnifox.

For the next two weeks, the Archaeology quest for Spirit of Eche'ro is available on live servers, so don't forget to get the rare mount before it's gone for 6 months!
How to Get the Spirit of Eche'ro Mount
1. Download MapCoords or some other add-os that displays coordinates in the game.
2. Teleport to Azsuna from the Stormwind/Orgrimmar Portal Room or use your Dalaran Hearthstone to reach Dalaran (Legion) if you have one in your inventory.
3. Seek out Archaeology Trainer Dariness the Learned in Dalaran at 41,26 and learn Archaeology if you already haven't.
4. Accept The Right Path quest from the Archaeology Trainer and make your way to Thunder Totem in Highmountain.
5. Talk to Lessah Moonwater to accept Laying to Rest. For the quest, you must collect 600 Bone Fragments of Eche'ro by rotating between four digsites in Highmountain. The exact locations with coords are outlined below.
Digsite 1: Darkfeather Valley (50, 44) Digsite 2: Dragon's Falls (58, 72) Digsite 3: Path of Huin (44, 72) Digsite 4: Whitewater Wash (39, 65) it takes roughly around 2 hours to get the mount.

Hurry up! You only have until August 21, 2024, to get the mount!

MoP Remix characters that will transfer over to retail will receive a gear boost!
With Patch 11.0.2 now live on Public Test Realms, you can copy over MoP Remix characters from retail! It appears all MoP Remix characters will receive a character boost so you can dive straight into action when the War Within expansion launches.

We can't unfortunately log in to the game with the MoP Remix char on the PTR so we can't confirm the Item Level of gear for max level characters. However, keep in mind that the gear boost will scale with your level, so if you're below max cap, you will receive gear appropriate to your current level.
When Can We Expect MoP Remix Characters to Transfer to Retail?
MoP Remix ends on August 19, so we assume the characters will need to be transferred to retail by August 22 when Early Access begins.

We've updated our to-do list for the second week of the War Within pre-patch. Find out what's new!
Get your piece of loot from the Great Vault if you've unlocked any slots the previous week. Pick up the weekly quest in central Valdrakken from Therazal to get your weekly spark fragment and Cache of Awakened Embers.
Pick up the second weekly quest from Kazra that rewards 1 Cache of Awakened Treasures for completing 5 Timewalking dungeons! 

The War Within launches in two weeks and many rewards will no longer be available. We recommend you to read our guide to learn more about them. The pre-patch event is still available, making it easy to level up your characters. Make sure to check out the rewards you can get and how fast you can go to Level 70. Blizzard made some nerfs to the bosses, so they now die faster. Darkmoon Faire is available this week. Make sure to use the +10% XP buff to your advantage! MoP Remix is still available on live servers, making leveling a breeze. If you're working on some of the rare MoP mounts, now would be a good time to level up your characters! Each char will get enough Bronze at Level 70 to buy one of the super rare mounts, toys, and more! If you're wondering what's faster Radiant Echoes vs MoP Remix, check out our comparison. All raids are Awakened until the end of the expansion, offering loot at an increased item level. Trial of Style ends on August 8. The Trading Post has been updated with new items for August. You will find them here. You can complete Time Rifts, Dreamsurges, and Superblooms for gear if you don't like the pre-patch event.
