Can't have your cake and eat pretty much. Yes, you can play however you want, but you can't have it both ways. No pet and the skills a pet brings is not, and should not be an option. All of that old stuff wasn't meant to be difficult, it was meant to get you in touch with the pet part of your class. The way blizzard intended. And it sounds like you just want to play the same ranger class that is always in every game. Surprise! Blizzard didn't go that route so as not to be the same boring class type. Go play those other "ranger" games if that's what you want. Roll another class that doesn't focus on the pet like the hunter has since vanilla.
