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

So will have people who the hardest actual content they would have done is dungeons thrust into whatever crazy primals or raids are in storm blood with little experience with those type mechanics

they won't be thrust into EX Primals and Omega Savage, they don't have to do those. they can still do Omega Normal mode and just do the Primals in the story mode.
