Maybe I'm misremembering (or it has changed), but I thought you could start with Expert in skills. I found it a bit difficult to find clarification in the book. I'm not happy with the slow pace of skill increases for everyone not-a-rogue if this is the case. Ranger and Bard can start with tons of trained skills, but after that it's dreadfully slow. Being able to start with Expert in skills would help reduce the feeling of a skill dam with no regulator. Also, maybe Rogues have too many skill allocations.
Any clarification about this?
unless there's an ancestry feat that boosts your effective training in a skill I'm not seeing any way to do this at 1st level.
That being said, the way the feat Additional Lore is worded, you could take it at 2nd level and then become a master of the selected lore skill at 3rd level.
As far as I can tell, there's no way to start Expert in /anything/ barring the few classes that do it for a weapon or armor category. And of course saves and occasionally Perception.
