Honestly I think that even a crit success for Bind would be dreadful, or at the very least really complicated. Think about it what is the process of binding as we understand it? Grafting souls on to the soul of the wizard, all well and good so far, but what happens when you graft on a soul that is larger and more filled with knowledge than your own? I do not know if anyone here read (or still recalls the Dresden Files) but taking from what I think the best we can hope from this is some kind of Fallen situation, you know a literal devil on Mathilde's shoulder, offering power and understanding in exchange for a little more power, a little more understanding.
I do not know about you guys but I did not vote to pioneer Orc corruption and I do not want Drycha corruption either.
The one thing that reassures me on that front is that you can apparently transfer a binding from your own soul to an object.
