The mount and pet tracking site, Wowalts.io has a new feature! You can now very easily check which mounts your character is missing that are going away with next week’s reset and patch 11.1!
Unfortunately, for some of them, it’s already too late unless you’ve already started the grind, like the 
Timely Buzzbee. As you can see below, the site tracks your missing mounts in general and now has a new scroll icon next to your character that shows a menu with the mounts going away. It also shows you how much time you have left to get the mounts!
The 
Delver’s Dirigible Schematic: Void isn’t technically going away, but it will become a low percentage drop from Zekvir, so you may as well get it while it’s a guaranteed drop! The site also shows the upcoming patch and Season 2 mounts if you want to check those out.
So head on over to Wowalts.io and check what you’re missing, both in this season and in general!
