Yeah, I tend to agree with regard to the letting people through that aren't Elven or Half-Elf. If he's stating that people who aren't of elven blood aren't allowed in the gate, the gate should be barred for anyone, not in a party with one, or who isn't one themselves. Especially considering that theoretically speaking this would be during the height of the Seldarine's power. They would probably be pretty insistent that their rules were followed, at least in their own city.
