Something like the last season of Dragonflight where all xpac raids were empowered. Just rerunning one raid gets boring so quick.
Imagine if they made a Timewalking-style event where all the raids in e.g TBC were tuned to the difficulty of the current tier and dropped appropriate loot, new mounts and toys, etc. along with some cool stuff to do in the zones, Then after 2-3 weeks, rotate expansion again.
It would breathe life into the staleness that eventually comes after you’ve cleared the current tier over and over every week without getting your BiS pieces.
Yes please. There are so many cool raids we just steamroll through for nothing else but a chance at a 0.1% drop rate mount.
