Talk about shoddy editing... I'm absolutely appalled.

If Moiraine is rock bottom that would make her as strong as Morgase, who is not actually a functional channeler i.e. spending all day trying to move a scarf. It's also likely that someone like Morgase can't even use an angreal, though Moiraine claimed she could.

It's more likely Moiraine can channel effectively but weakly, like Sorilea... but I digress. It seems like any sort of previously organized system died with the author.
