With regards to Illusion: Frenzy, Rout, and Pacify.

It should be noted that these numbers do not take Necromage and Champion of the Night into account, meaning the values you see here can potentially be even higher if you have those particular perks/effects.

It should also be noted, however, that Dragon Priests are usually encountered as solitary enemies (excepting Ahzidal and Rahgot), so fury spells probably won't matter much in the long run.
