Personally, I'm sad. I would have loved a long term goal in battlepet. I miss the early mop, where I had to hunt, and lvl a lot of pets, now, it's just super easy to hunt and lvl a pet. Beside the expansion rush, during all expansion, pet hunting and lvling is really quick. I don't even test 95% of the new pets, I just get them, blue stone, few tamers and hop lvling stone.
Instead of searching a good way to implement the epic battle stones, they just drop it. Well, I'm not surprised.
- They could have offer 5-10-15 purple stones with a quest chain, to help bring a few importants pets epic.
- They could have put a new xp bar to lvl the rarity once the pet is 25 (like the garrison follower), and just have the stones as a bonus.
- They could have made it so they stay blue (in stats) in PvP matches or against some tamers.
As for listening to player feedback... Well... I still remember the garrison / flying / shipyard / apexis... Basically WoD and all the non delivered content (brawler anyone?). So it's not because they reverse a stupid and useless nerf (water striders), that I will trust them and their ability to listen to players. Nerf a mount which is a big pain in the a** to get, just to make relevent their fishing artefact... and trying to justify this by : "players only use this mount, it's sad"
