Meh. I tend to take all of the flavor/fluff aspects of classes and subclasses with a grain of salt and adapt or completely rewrite them as needed, using the actual mechanics as inspiration for things. Classic example is the barbarian, which WotC seems to think is necessarily a primitive, tribal character but could easily fit into a great many character concepts that have nothing to do with tribal culture or anything. Same for this class - just because Crawford colors it that way doesn't mean it ought to be.
Example, the character I've been working on from back when it was more Underdark-oriented: a human who watched his town get ransacked by an incursion of duergar slavers on a raiding mission through tunnels that connected to the town's quarry. Spent his early adulthood wandering around, trying to figure out how to access the Underdark to search for his lost friends and family and/or exact revenge on their captors, learning some rangering skills along the way as he looked for entry points and clues. Eventually, he came across a city of elves who regularly sent expeditions of elite Deep Stalker units to push back against the forces of evil from the Underdark that threatened their own space. After many trials and great effort to prove his worth as a scout and soldier, they eventually let him join along, earning him the nickname "The Blind" as he was the only one of their number without darkvision. Years later, his darkvision eventually grew to match their own, through some combination of gradual adaptation and magic, and he was as fierce a hunter of vile Underdark creatures as they were. As time passed, he came to realize that his elven companions were interested entirely in the defense of their own city and had little interest in delving deeper to hunt for likely long dead or broken slaves of the duergar, especially ones not of their own kin, so Vorn the Blind left in search of others who'd be more helpful allies.
So sure, lots of ways to make a loner-ish character into a team player.
