The next expansion, Midnight, is scheduled to go live on March 2, 2026.

It's now up on the PTR for testing.

There will be a pre-patch for Midnight on January 20th and I suspect that that is when we'll experience the class changes that are noticeable in the PTR.

It would be a good idea to clean out your bags before January 20th and get rid of gear that you don't need as the gear vendor prices are going down in keeping with a major item level squish.

As an example of the item squish, one of my characters went from item level 713 to 153 when copied to the PTR.

Here are the new ranges of item levels for the different types of gear:
Veteran: 108 - 131
Champion: 121 - 144
Hero: 134 - 157
Mythic: 147 - 170

Note that, at least until the week prior to March 2nd, you can expect that running Delves, Raids and Dungeons will result in the same type of gear drops and Vault awards (Heroic, Mythic, etc.}.

I expect that we will lose our Valorstones and all of our Crests at some point, but maybe not until the expansion goes live. So, try to spend your Crests and Valorstones soon.

When Midnight goes live, you will be able to level from 80 to 90.

To help with leveling, you may want to visit the Darkmoon Faire the week of March 8th and exchange some of your Darkmoon Game Tokens for Darkmoon Top Hats which give you 10% experience and reputation gains for 1 hour. But don't buy too many as they only last while Darkmoon Faire is up.
