This brings up the idea of figuring out a way to differentiate the Ranger by making it the epitome of a mid-weight "skirmisher" class. I still think that a ranger on their own should be the highly alert class (rarely surprised, hard to get the drop on), and mostly focused on ambushes and guerrilla warfare tactics. However, it should also be that a Ranger working with allies, whether that be their animal companion, a rogue, another ranger, or an entire party should be a terrifying thing to come across.
I'm not 100% sure how to go about achieving that mechanically (esp. in 5e), but I like the idea in principle.
