Since the release of 5E, every publisher of a more complex and/or difficult game is about to find that out to their peril.
The appetite for games of 3E or 4E levels of complexity/difficulty just isn't there anymore.
ESPECIALLY on the GM/DM side of the table.
Add a rule that makes charbuild more intricate, fine. It likely affects one player, and its her choice to pick something that must be actively remembered during play.
But it's no coincidence monsters are vastly easier to run in both current games.
One significant difference between PF2 and 5E is that Paizo filled their game with lots of niggly little subsystems (lots of rolls, lots of small modifiers, lots of decision points) the GM can't easily ignore or downplay.
I'll elaborate on demand.
Pathfinder 2 comes across as a game written by people who completely and totally missed the why and how of 5th Edition and its success.
It's a game designed to compete against 3E (=PF1) and 4E. I'd say it is successful at this. But that isa sadly irrelevant unless you wind back the clock five years or so...
