Maybe he just doesn't trust his whms or schs. There are plenty of lacklustre healers out there. I know of one who goes afk during a fight and then leaves you wondering when/if they will ever come back. Or they afk without warning pre-pull. Granted they do have children and thus get child agro from time to time but even when they are there you might as well have a mule of someone who doesn't dual box very well because there isn't that much difference.
