I don't think Quira's doing an amazing job. No offense, but... she isn't. She made things a bit too confusing to start off, and when asked to clarify just served to worsen the situation. She's not being strong ehough, either; it's clear she wants to be in on the community aspect of the game, but in doing so is giving up her respectablity as the game's 'God'. The God shouldn't talk so freely among the mortals, it makes everything fall apart.
On another note, I think Jakko's a vampire. He seems very quick to try and confuse everyone as badly as possible. He knew full well that the whole Guardian thing was a technicality, but he argued it to the end in a bid to set everyone off their bearings.
