[Dresden Files] Lots of wizards died in the war with the Red Court. Like lots. Why didn't we see wizards doing amazing things with their death curses?

It seems like good opportunity to do something great, but no one seems to do it.  One of the Denarian carriers, Cassius, pulled out that "Die alone" death curse so it doesn't need to be just pure destruction. Donald Morgan was a formiddable wizard. Why didn't he do something amazing in his last minutes?

Death curses are not the effect of a wizard dying, contrary to popular belief. It is the final spell expended by a dying wizard, fueled by all his remaining life force and magic. So, for a death curse to have any effect, the wizard must have time to formulate his curse and choose his target. If death was instantaneous, or the wizard is somehow incapacitated from conscious thought before dying, then he could not cast his death curse.

In the war against the Red Court, the wizards were fighting an enemy with superior strength and speed. Most likely, after the first few death curses, the vampires adapted their tactics appropriately. Also keep in mind, more than a few nobles of the Red Court were spellcasters, in addition to whoever the Black Council sent to aid the Reds. They have more than enough experience to formulate such tactics.

As for Donald Morgan, who was he going to target with his curse? The only appropriate target was the traitor that he just killed mere seconds earlier.
