The quote comes from Arthur C. Clarke. He was an assistant editor of Physics Abstracts, and president of the British Interplanetary Society. His book, The Exploration of Space, was used to help convince Kennedy that humans could go to the Moon. As one of the most influential science and science fiction writers of his time, in 2000, he was made a Knight Bachelor by the British Crown for his services to literature.
Maybe watch who you call an, "ignorant hole person."
More importantly, the quote necessarily entails a much more interesting statement:
Any technology distinguishable from magic is insufficiently advanced.
I'm still scratching my head that I can post some amazing worldbuilding and get a couple of pages at best, but say something about core dnd classes and we're up to 17 pages.
Telling people (even if only by implication) that something they care about doesn't
deserve to exist is much more likely to stir up controversy, and thus attention, than unobjectionable fare.
What is the purpose of the ranger and what examples do we have from fiction?
The archetype of the ranger is a survivalist and a hunter: someone who walks the fuzzy boundary between civic (or at least organized) culture and the chaotic wilderness, and someone who is adept in bringing death to a target, be it against sapient or savage prey.
Superhero examples are actually quite nice here. Green Arrow and Hawkeye are great urban Rangers. Robin Hood is extremely flexible, so you
can flavor him as a Ranger, but he might also be other things (e.g. the later interpretations that make him specifically Robin of Locksley, a displaced member of the nobility, might warrant Paladin instead.) Boba Fett is a sci-fi Ranger (as many bounty hunters are). Atreus, aka Loki, from the new God of War games fits fairly well with this idea, especially once he starts developing his Jotnar magic. Ronon Dex, from
Stargate: Atlantis; potentially Van Helsing, if expanded from exclusively vampire-hunting and into general nasty-monster hunting; "Crocodile" Dundee; Katniss Everdeen from
The Hunger Games; H. Rider Haggard's Alan Quatermain (of
King Solomon's Mines fame); potentially the image, and part of the actuality, of Teddy Roosevelt and other "big-game hunter" naturalists; etc.
As far as implementing this, all I can say is, the goddamn coolest thing I've ever seen a Ranger do happened specifically in 4e. Our party Ranger got into an almost mesmerizing dance of death with an elite foe, each of them dodging and weaving around one another as they strove to strike the final blow. Watching the two of them repeatedly have a "au contraire" moments back and forth as they did their turns was almost more fun than doing the entire rest of the fight that I and the other players were taking care of.
