Initially, I overlooked Vale of Eternal Blossoms as a place for leveling pets because I wasn't satisfied with the reliability of Flying abilities (FYI, they are strong vs. Aquatic types and Vale is overwhelmingly Aquatic, but they tend to have a moderate => high chance to miss or hit 1-3 times). However, the Brilliant Kaliri is such an effective counter to Aquatic pets that I now level against wild pets on days that I've finished my tamer circuit exclusively in this zone. Peck can usually 2-shot anything while Peck and Predatory Strike guarantees a kill, save for very high health rares and well-timed heals. Additionally, above 50% health the Kaliri will always strike first, meaning you can - ideally - wipe out an opponent for every hit you take.
Wanted to share this info in case some of you are looking for a change of scenery to level or a place to grab an Aquatic stone.
