I've seen it brought up that an Aegis isn't important because magi can deal with the problems. Of course, they can. And I'll submit the Aegis is important for the covenfolk, primarily, and it keeps the anklebiters away from the covenant so that the magi can spend their time concentrating on their important work, rather than deal with the constant interruptions from low might creatures getting into a covenant. An Aegis20 is pretty easy to cast and learn, and getting a couple of people to commune on it makes it easy. Give it to the Cautious Sorcerer to learn, invest some time into mastering it, and it becomes very easy to cast reilably. And many people believe that one level of mastery mitigates the risk of all botch (I'm not one of them) that was heavily debated in this thread.
And if you're moving a grog (rather than instantaneous translocation) you don't need requisites, the other items get moved as a consequence of the body under or holding the items moving. But if it's a teleport spell, yes, requisites are important, but these are casting requisites, and have no bearing on whether the spell can be learned, or even if it should be in the list...
