Binding familiars and assistans in the lab

I've noticed that metacreator does not allow using assistants to aid in the work with familiars, and queried Alter Ego about this, and got this response:

Since this was something I would never have read from the rules as printed, I thought I should share it with you.

I personnally am against this ruling.

Having your Master help you to bind your familiar is a nice story hook. I'd hate having that option removed.

Yes... and what if you have an apprentice? Or does Metacreator actually treat that differently?

No difference there - the way metacreator does this, it disallows any assistant. And as far as I understood it, they do it like this after discussing it with mr Chart.
