With BlizzCon pretty much in the books for 2015, from the summaries here, I don't recall the devs mentioning anything about Pet Battles in Legion. Does it seem like that Blizzard will put this feature on the backburner, providing only minimal new content? It sort of felt the same way with Archaeology in WoD, as the goodies were not that spectacular. I did appreciate the catch-up mechanics for Pet Battles and Archaeology in WoD though.
