I just ran a short adventure that involved a cabal of wraith-sorcerers led by a dread wraith. One of my PCs decked himself out feat-wise enough (15th level party) so he could weild two greatswords (it was a short campaign for fun), one of which was disrupting, amongst other things. Between that and the party paladin's ridiculous turn checks, wraiths were fleeing and being destroyed left and right. This was good, because they were just giddy about it.
They really had no trouble with any amount of the lesser wraiths, but one dread wraith proved a serious challenge for them. Why? Incorporeal undead with
Spring Attack, in a small room with a 60ft. fly speed.
I said that each of the three characters could only ready actions against the section of wall that was in their field of view at a given moment. I would decide where the wraith was going to fly out of next, then I would ask them where they were focusing their attention, and what actions they had readied. With three characters and 6 surfaces in the room (4 walls, ceiling, floor) it became a somewhat comical battle of attrition as the wraith popped out, attacked, drained some constitution if someone failed a save, then flew back into the walls. Occasionally the PCs would get their readied attack off, but with incorporeality (50% miss chance for magic weapons), a +14 Will save and 16HD, the wraith wasn't overly intimidated by disruption weapons or turning. Finally the wizard readied an action to box themselves and the wraith inside a wall of force the next time he flew out. He tried to retreat back into the wall, and ran right into it, to which the wizard responded with cackling. They finished it off fairly easily then, but it was fun to challenge such a well equipped 15th level party with a CR11 creature.
So, in short, against incorporeal undead, I don't think disruption is too overpowered. It's just really fun for whoever's using it when it does work. Something about 'save or die' must really be appealing
Now, the final encounter in this little scenario, they knew, was going to be against another more powerful type of undead. The character with the disruption weapon begged me to have it be corporeal this time. I had already picked it out (a Nightwalker) so I told with a smile to not worry. He was pleased when he saw that it was corporeal, and opened up a whole load of damage on his first full attack (something like 80hp). Of course, the Nightwalker can't have this damage machine hitting him with this disruption business (lest he roll a 1) again, so he uses his Crush Item ability to utterly destroy both the character's greatswords

The jaw-dropped expression on his face was priceless.
Undead. Such good times.
