Is progressive content or the community to blame for player skill gap?

[Dreggit]

As somebody who is the new player who recently got into 3.0 content, I have done every single extreme Primal boss synched, repeatedly bashing my face against a difficulty wall, until I understood the mechanics and was able to complete it with a random Duty Finder party and it is some of the most fun that I've had in this game

and when somebody in those duties say screw this or get good scrub because I'm a newer player who is actively learning mechanics who watches videos of fights before doing the content why should I be bashed for trying to learn to be a better player? I would rather repeatedly fail and have fun doing so then just cheese the content for no reward.

To have come so close to beating Ramah Ex, I know that when I do it'll be an awesome feeling just like how it felt beating Titan extreme with a random Duty Finder group.
