Having played d&d since the red box, through Ad&d 1e, 2e, 3e, 3.5, and PF1, I have to say it bothers me, but it’s about feel rather than detail.
It wouldn’t bother me if Magic Missile suddenly did d6 rather than d4 damage. I’m not even fussed if a classes fundamental abilities have changed. But it did bother me with 4e that an RPG that supported a predominantly ‘theatre of the mind’ game suddenly became a grid based miniatures game modelling a MMORPG - to the point where I jumped ship to Pathfinder after a literal lifetime of playing d&d.
I’m still struggling to place PF2 - some of it feels familiar (good), but other parts feel ‘not d&d’ - so struggling to love it at the moment. At least it doesn’t feel as alien as 4e/5e does to me, so I’m hopeful it will grow on me with more play. It took a while for 3e to feel like home as well...
