Mystic Adept, My first try at making one Options

The fact of the matter is there is no reason a spirit wouldn't use edge to prevent binding. RAW says if the drain knocks the mage out, the spirit will turn on the mage and try to kill him. If it hates it enough to kill the person doing it, it hates it enough to use edge to prevent it, unless using its edge sucks worse then something you're willing to kill over. And yes, the backup mage to fend off pissed off spirits is a good idea.

Given the impact, if the GM is going to plan on having spirits resist binding (and summoning, if they choose) with edge frequently, then I would hope that they tell the players that at setup. It will shift the spirits down to the lower power ones. (Many of which are still useful.)

I had tended to assume from the way the book was worded that it was not the norm. But reading it the way you do seems equally valid to me.
