Aasimar get +2 Wisdom +2 Charisma. So its not too out of whack. It looks really bad, but if it was Mental and Physical, with one of the scores being Strength or Charisma it would be way stronger.
The +2 to Diplomacy with the Charisma bonus and the +2 to Perception with Darkvision and Daylight casting makes the race. The rest is cool, and nice to have, but it seems stronger than it really is. It isn't bad, its nice to have, but it isn't great.
Like, people see the resistances and freak out, but they don't even raise an eyebrow when they see a Dwarf getting a +2 to their saves against pretty much EVERYTHING and having bonuses in 2 save stas. Look at the half elf. They get +2 against charms and the ability to trade in Skill Focus for Iron Will. Both of those are so much more relevant than 3 resistances, even in they are at 5.
Oh, you might not have known there are a trillion different racial ability changes and favored class things you can do. Maybe Aasimar will get some support in Ultimate Races, but I wouldn't count on it.
