The point is the lore is druid revere nature. Even dark, wild, or evil ones.
A ranger does not have to. A ranger can be played straight and be indifferent, adversarial, antagonistic, or even openly hostile to nature.
A ranger can employ tactics and actions a druid would never do. They can employ all aspects of zoology, cryptozoology, herbology, geology, etc.
What aspects of herbology are denied to a druid? Where do you see that listed? Where does it say that Druids can't use all aspects of zoology?
Heck, you can play a cleric or a paladin who is indifferent or antagonistic to the gods, does that mean that the cleric and the paladin have nothing to do with the gods? Yes, those types of rangers can exist. So what?! You can do the same thing with Druids.
That's what the ranger lore.
You might not like it or think it is outdated. But that what the lore it.
Druids form a deep connection with nature and thus interact wih it primarily with match.
Rangers' connection does not have to be deep and interact with nature primarily with skills and enhanced that with magic.
Okay, so Druids make a connection with nature and it MUST be with spells and magic.
Rangers make a connection with nature, but they can do it with skills that the Druid can't, because Rangers are civilized and Druids just have secret knowledge of nature that no one else does? How does this make sense to you? That isn't even what the Lore states.
And?
Evil druids still have to respect nature and don't get artificial nonnatural spells by default.
Rangers don't have to make a deep connection to nature.
What the heck is an artificial non-natural spell? Something like Charm Person? Druid list. Find Traps? Druid List. Locate Object? Druid list. Feign Death? Druid List. Dispel Magic? Confusion? Blight? Polymorph?
Or is that the ranger gets these unnatural spells? Like.. what? Hail of
THORNS?
Lighting Arrow? What parts of the Primal spell list given to rangers is unnatural and artificial here?
Also, seriously, expand you conception of Druids. Evil Druids can include:
"Nature is red in tooth and claw, so since I'm the strongest I kill and take what I want, even subjugating animals to my whims."
"Nature is about adaptation. I will use my magic to force these creatures into new, superior forms, making them stronger than ever to make the ulitmate life form"
"The natural state of the land was the flame and burning rock before life. I will return it to that!"
These aren't positions of balance with nature, but they make sense for EVIL druids, because it turns out EVIL doesn't often care about things like Balance. Turns out that is kind of EVIL's whole schtick, is being out of balance.
Seriously, it is trivial to make a druid who is a rancher or a farmer, and fit perfectly within the druid aesthetic. You are making a distinction for the sole purpose of avoiding the realization that spell-less rangers would logically lead to spell-less druids, something that no one wants.
