I'm the same, I have to learn the "dance" in the dungeon, and I do, I get better each go, I only have T13 to clear (I have been maining as SCH). But most people want you to have encyclopaedic knowledge and know what to do.. often those people have already progressed further than you so assume you know too.
This selfish gear/win focus in PvE is what I think makes it tough as blame/expectation is high. I'd like to dungeon & raid with friends and progress as friends, not have friends become competitors.
I do like doing new content with no spoilers and learning the fights, then if/when you do see a video it makes more sense.
On the learning side, I am happy to help with that, I can bring a geared tank or healer to help someone learn things with out the fear of letting others down.
