There are other factors SE introduced in 6.1 involved, it is not just CC.
There is new category I called animation lock.
Let me be more specify.
Any CC can be remove by Purify is traditional CC
There is another school SE introduced is put your target into animation lock and target's action bar will be disabled or can not be remove by Purify:
Phantom Rush
Meteor Drive
Miracle Nature
Contradance
There are many more but I yet to discover during my solo in Frontline.
Overall, you can't touch CC because there are two schools.
The best thing is to apply 5.0 version of countermeasure to bring down Ranges to even with Meeles
