I think the boon/bane of 5E is that narrowing the number of modifiers and choices makes the game simpler but it also means that each choice becomes way more significant to the system. PF having lots of choice points means you can be much more flexible and not damage your PC

Unfortunately being an Herbalist or an Entertainer isn't a cute little RP thing if it permanently determines your accuracy/damage/spellcasting DCs for the rest of the game Custom is the way to go but it removes so much flavor (and a lot of things for them to publish in the long term)
