I think generally, the "weaker" templates are there as entry points at lower levels. For example, you could take a minor talent and progressively upgrade it through focused practitioner over sorcerer to wizard. Pretty much like channeling and ritual are gone entirely, once you take the upgrade to evocation or thamaturgy.
So yes, it is weak, but only because it is one of the templates that will mostly be there at the lower powered end. They will either upgrade or stay out of the major supernatural conflicts (for the most part, anyway).
Also, I agree with the 'guidelines' character of the templates. Thanks for the video, admiral
