Usefulness of certain CS Pet Equipments?

Basically, only buy pet equipment if you think you can make back the nx worth in mesos. For example, if you train at himes frequently, you'll be moving across the map constantly, meaning that wing boots might not be useful. If you train at himes with a partner, it might be worth it to get magic scales. If you snipe things on top of the jeep at mysterious path 3, you might want wing boots. These are just examples, by the way.

I'm personally perfectly fine with item pouch only though.
