Also seeing as discussion about aasimar power levels is afoot I might as well add my two cents (though playing as
an aasimar, it may well seem like I'm whining, lol). I think that the key word to keep in mind is versatility - the aasimar is very situation specific, with their Celestial Resistance and Spell-like ability (a whole 6 RP total), compared to the standard races who have abilities that work under almost every adventuring situation - I myself was originally planning on having Eran as human for that skill point and bonus feat, before choosing otherwise for flavour's sake.
By contrast, the aasimar can only really use their ability score bonus, skill bonus, and darkvision under most circumstances. The resistances give an advantage when it comes into effect, but otherwise; oooo, big sword... nuts. I do think that the Spell-like ability has the chance to put the aasimar a tad above their contemporaries (especially with the variant aasimars).
Still, those are just my thoughts and I'm not one to quibble, so if something needs to be dropped, dropped it shall be and you won't find me drawing up a new character because of it
