It’s quite intimidating to scroll through the list of what Patch 6.1. brings. However, almost all of it is just minor changes; it is, so to speak, the smallest biggest patch in the world, a lighthouse feature is missing:
The perhaps biggest change for Twinkers: Heirlooms are making a huge comeback. They will have their own tab like toys, mounts, and pets.
The Blood Elf models are new now, and changes are also made to other models.
Somehow, Patch 6.1, even though it brings so much, is missing that “one, decisive” feature that is really new. That’s probably why it’s so hard to remember exactly what the patch brings. The Blackrock Foundry has been up for a while.
