Well, you're also weak to normal anti-outsider spells. Like planar binding.
Yeah, but so are all the base races, and they're nowhere near those stats. Granted there's a couple that could arguably be close, but the human definitely isn't. I think I remember talking to Gawain about the star elf, and how I couldn't believe its power by comparison. I think that's the problem. Comparing them to the base races and not the newer ones that are out.
That's because you're only looking at the stats (though if you think stats is all there is, Dragonborn Water Orcs have +4 Str and Con, -2 everything else, plus they get their choice of wings, awesome vision modes, or a breath weapon). For raw power, other things are more important, such as feats (Humans) or access to special abilities and PrCs (Kobolds, Gnomes).
