"halflings are still quick and nimble" except they aren't - because that quickness was represented in the form of ability score bonuses. Now they are just short humans who are missing their 3.5 / pathfinder feats.
Indeed every species is a human with some cosmetic differences - except actual humans which are mechanically disadvantaged.
But, to be honest, I blame WoTC not Larian - they are anxious to move the game to 6e. While I support their intentions and some of their changes - like replacing the problematic word 'race' with species - but I think they are going about this the wrong way.
Yeah... The design philosophy seems to be "remove features but don't replace them with anything. Leave it up to the DM and/or player create mechanics & base worldbuilding, or just use your imagination and pretend!"
At this point I'm hoping that someone will design a setting as rich and compelling as Faerun because WotC keeps screwing up.
I mean...
Pathfinder 2e and Golarion?
