Why not Barb as the lowest if I may ask? Rage and go hit stuff, seems like the simplest class to play to me.
I like this summary of each class, it includes a 'difficulty' rating for each:
I don't see a specific rule for this, but I would just let them ignore the restriction of picking a certain number of archetype feats before selecting a new archetype. There's nothing preventing you from picking a 2nd level feat at level 4.
I'd really love to support Paizo and buy all the cool Foundry content, but man 60 bucks is a lot.
Never enough. When I die I want my kids to be burdened with wondering what the heck to do with dad's dozens of boxes of rpg books.
Pathfinder 2e didn't work out well in my main group, so Ive started running Abomination Vaults for my kids. It's a lot of fun but the younger ones drop in and out, so my oldest ends up running all 3 sometimes.
