I have always considered that KI would eventually introduce the ability to have a second pet, without it being too overpowered. I also wondered how they would introduce such a concept. I always thought that if you were a max level crafter, gardener and angler, you would have the "Experience" (in the eyes of Ambrose) to carry a second, smaller pet. This would include an extra pet slot for your character, but here's the catch, the pet can only have 2 abilities, and they are not allowed to be the same as your 1st main pet. Any thoughts?
