Blizzard has added a new meta-achievement for the Battle for Azeroth expansion in Patch 11.0.7. Upon earning 
A Farewell to Arms, players will receive the 
Jani’s Trashpile mount.
Why the Jani’s Trashpile Mount Won’t Be Easy to Earn
While seasoned Battle for Azeroth players may find some achievements familiar, the journey to completing A Farewell to Arms is layered with challenges. Notably, some components rely heavily on RNG, meaning the required World Quests and item drops won’t always be available. For example, 
I’m On Island Time requires completing specific world quests that won’t always be up, while the notorious 
Mecha-Done achievement depends on random drops from rare mobs and nobody can say for certain when you’re going to finish the achievement!
