Something else to keep in mind on any mob with a badass DS is Shielding Resistance AA. For any dual-wielding chars, throw a non-weapon in your main-hand till it gets dispelled. With 5 Ranks of SR you'll be immune to the DS with your off-hand. We used to do this on the blobs in Solteris if anyone remembers those bastards from Live. I use one of the clicky summon food / water items from Vex Thal (Dulak on EZ) personally.
Btw on warrior if you put in a non weapon in primary hand OR remove primary hand weapon you will not swing off hand.
Ez server has all kinds of cute little things like this.
The best dispell is Monk and I say that because xiggie mains a monk. So I just say on vent "bitch, dispell, now" and its done.
Sammich!
