Right now from what I experience in game and what I read on the forums Ranger pets deal too much damage and are too squishy. Rangers should account for about 60% of all damage and health and pets should account for 40% of all damage and health. Having almost half health sounds unfair? Make the damage mitigate from the ranger to the pet and vise versa. That way the health pool of the ranger and pet will be linked and both can survive longer.
Dumb idea? Give me yours!
