I also think these fellows are too powerful for the game and don't like to use them - especially the grand inquisitor.
Unfortunately, the AI likes to use them against you.

What someone said about hiring a muslim merc unit applies. Of course, I found that these merc units attract other nation's inquisitors. They get all excited about those 0 piety scores. But my inquisitor gets first crack. What you can do is take the merc unit, and hit 'em with a spy to try the general, and at the same time, burn 'em with an inquisition. The spy goes first, and if he fails, the inquisitioner does his thing. Lather, rinse, repeat. After a few years of this, you'll have an experienced spy and inquisitor, and can send them both off to other duties, and start on a new pair of guys.
