How can Blizzard revamp Northrend and make it relevant again?
I think they could make Northerend more relevant by giving the Necrolords some business out there! Dead DKs working with Double-Dead DKs! Hash brown party time 
Why would they need to?
- the titan keepers are all useless now
- Yogg-Saron is dead
- Bolvar is playing hero in another plane of existence
I’m disappointed that didn’t say gnomes instead of Necrolords. Wild you’re slipping!
Shadowlands itself stop with 9.1. Then we come back to Azeroth and now have to deal with Zovaal gooning it up on this side.
I think the gnomes should get awards for being cute while the Necrolords go do their thing in Northerend 
To make it relevant again as the questions clearly asks.
Shadowlands should’ve been an expanded Northrend, where after the veil broke, the Mawsworn terrorized the countryside and we found an entirely new continent up there where the big bads set up shop. We could’ve traveled through the breach in the veil for Torghast and an end game zone, but the Jailer was trying to destroy Azeroth instead of all this bs in an entirely different realm of existence is happening.
Not bad ideas actually.
How about it just be left alone and appreciated for the fine slab of land that it is?
But why? Unlike EK or Kalimdor that originally had areas which were unreachable or unused, all of Northrend has been seen already. There’s no reason it needs to be relevant again.
shadowlands invasion ? Like those with cthun ? 
Shadowlands ends with a losss on our part and northrend become jailer territory ?
Then why are you part of this thread if you don’t have any ideas to share? That’s the whole point of the thread is for people who have ideas to discuss them.
I asked a question that hasn’t been answered yet. Why only Northrend? Why not also Pandaria, or Broken Isles, or Zandalar/Kul Tiras? Or Outland? or AU Draenor?
Because I haven’t gotten around to posting those yet.
They could always blow up the sky 
Ala the Matrix?
At this point Blizzard can just go Destiny 2 route and delete all the areas except Oribos and Korthia from the game. This will make the installer size maybe <10 GBs and the gameplay loop will effectively stay the same.
This whole approach of abandoning old content and making new areas has made the game incredibly small for something called “World of…”
Turn it into candy land and add the Wonkamancer class.
This! 10/char
