About the loot pets: Right now it seems that it's possible to accidentally drag them off the screen to where you are no longer able to select them - essentially losing them forever. A quick fix for this would be a button to reset their location.
Fun, but more than a bit repetitive. Seems designed mainly as a vehicle to nickel and dime people for cash - though the F2P model is, thankfully, far from the worst I've seen.
