I love the fact that you don't have to train your pets! While I think shooting the pet out of the cannon, is a hoot, (first step for any new pet in training), the rest gets intensely tedious. Please PLEASE do not change the current programming for pets! I have a Golden Stingtail, and am so loving it, she is a brave little fighter!
I like not having to train my pets as well. My little Chameleon is level 36, like me, and can do almost 100 damage. While that isn't a lot, it's dodge rate is so high, that I think it has only died once since I got it 6 levels ago.
