redefining elitism to fit your framework, does not in fact redefine it. I've seen all of this before and what you a re talking about is not elitism, it's veteran player fatigue which brings with it a nasty dose of intolerance for other players, new players and anyone/anything that does not meet the exact specifications of the fatigued veteran player at that time.
The attitude that demands others watch a video before playing is selfish pure and simple. Many players wish to experience content the first time by actually playing it.Shocking I know, imagine that wanting to play this game instead if simply viewing it on You Tube....
Elitism stems from the elitist who believes themself rightly or wrongly, to be superior to others, not player fatigue.
Dressing up the bitter intolerance that comes from the fatigue as elitism doesn't make it elitism, even if rationalizing it that way makes you feel better about your self.
