Relaxed Intensity
This worries me. I haven't played a PC in 25+ years and I am not a skilled player, nor do I have a desire at this time to be one. Is it your opinion the PF2e is not a casual game? If a jumped into Society play would it frustrate the group if I wasn't a skilled player?
I cannot speak to every group, but my experience here locally in the Denver area is that Society tables seem to be very welcoming to new players and willing to show them the ropes. That being said the content is tuned pretty hard and most GMs will let the dice fail where they may. When things go badly most players take it pretty well. I have had a lot of fun in failed scenarios.
Side Note: Pathfinder Society tends to be rather close knit. I find you get to know people pretty well and make friends in a way that happens less often in Adventurer's League which can feel more disposable.
