Well I think along the terms of stealth for a ranger is a nice idea but would it not be more along the lines of Survival in the sense that the ranger would put up some type bind made from their surrounding thus allowing the ranger to effectively "Quote" Stealth at a distance.
My thoughts on the hole hunters bond with animals is iv always enjoyed the idea of having wolf, hawk, panther etc... but it can become a bother when having to not only manage your self and a pet with mmo's so i think making it so that depending on the type of animal bond you have would have its own added difficulty
for example:
Easy
if you wanted to have a pet but did not want to deal with having to control your pet in its actions you could take form the list below and gain ability's based on the animal
Hawk - Scouting bonus/ less penalty's with longer ranged shots
Snake - slow targets allowing you to gain more distance from melee/ immunity's to some poisons
Normal
If you were looking for more control over the actions of pet in the sense of basic attack and defend the list below could be some of the options
Bear - keep the attention of target/ keep multiple targets attention
Giant Spider - Hold Target in place/ poison targets
Hard
If you were looking to really wanted to set the bar you could choose an animal that would allow you to set up the style of attack and defense from the types of ability's by priority and have an action bar for their skills as well and the list below could be some options
Wolf - deal out burst of damage/ be used as a mount
Panther - Sneak attack/ Be used as a mount
but this is just a thought for possibility's and just another thought to throw out there I think it would be awesome if rangers that team up with the same type of animal for example:
if team rangers all had wolves for pets the could attack targets in a pack like manner same with other types of animals but this is just a thought.
and I'm sorry that this might be a long read but that is my take on the ideas flying around
