In terms of the Ranger, WotC surveys seem to indicate the mystical as a core element to folks in general:
"There are two, interesting elements that emerge from the survey. To start with, the 2nd and 3rd edition versions of the ranger were the most well received versions of the class. Those two versions mixed an animal companion with wilderness skills, spellcasting, and a unique fighting style focused on wielding two weapons. 3rd edition added an archery option. They seem to match closest with the ratings given to the design direction outlined in the ranger article. The concept of the wilderness champion and defender along the lines of a paladin isn’t very popular, but people do like a ranger who can survive in the wilderness through a combination of skill and magical abilities.
"Given that background, it’s no surprise that a ranger class that de-emphasizes magic and lacks a full-time, in-the-flesh animal companion received fairly poor ratings."
