The cleanse is never what mattered, maximizing potency under Berserk's effect is what was important. So even if the Pacification is instantly removed by Paen, you still want 9 GCDs under Berserk.

I agree, that is the most important part, but before that 'buff' anything more then the bare minimum was almost completely wasted, since most if not all of the extra time you gained was washed out while sitting in pacification.
