I am super excited for it! I love that PF2 is shedding the OGL baggage. Sure, losing the drow stinks, but that's the worst of it from my point of view.
Refocus is better? Yes please.
Removing the historic D&D alignment system? Great, I always felt like humans are more complicated than 1/9 moral archetypes.
Attributes are now just the modifiers? Finally.
Nephilim to cover planar offspring? Dig it.
More versatile heritages? Love it.
Revisiting all the classes and making improvements? OMG I can't wait to see the new and improved Witch.
