Chaos Zakum, how hard is it?

I went in with a full capable squad. The dispel was seriously crazy.

I think we lasted 10 mins before we were down to a handful of nls/bms/bishes and all the warriors. Downed 1 arm.
I don't think those saying how easy it is appreciate how much time getting dispelled wastes. Every class has something they need to rebuff and it adds up to a lot of time.
Auto-skill pets will make it infinitely easier.
