D&D 3e opened the door (in D&D-land) to any race/class combination. To encourage archetypal combinations they introduced the ‘favored class’, where characters of each race could (potentially) enjoy reduced experience point penalties when multiclassing with their favored class — with no effect whatsoever if they didn’t multiclass at all, regardless of class or favored class.
Pathfinder did a better job of it, I think, allowing a small but not overpowering benefit (+1 hit point per level or +1 skill point per level of favored class). Things have changed more from there, with races having more than one favored class, and with (race, class)-specific benefits.
Now, it looks like core races have ‘favored class’ options for _all_ core and advanced classes, and I’ve seen third-party publishers include ‘favored class’ options for all the core races (which I think is a good thing if ‘favored classes’ are a thing).
I’ve asked a question similar to this before, but I think circumstances have changed a bit. ‘Favored class’ options that exist for all combinations seem misnamed.
Perhaps it’s time for racial archetypes on the classes. They’re still optional, so you’re not forced to take them, but half a half-orc bloodreaver (barbarian archetype — and others are possible) instead of picking between +1 hit point per level, +1 skill point per level, or +1 round of rage per level.
