Why Confusion Erasing BATTLE CRY!

Hi Dear Korlash or Aleenia

I want to talk about a horrible case.You know berserker warriors are using cry echo skill.So you must use battle cry skill for it works when priest are using confusion skill battle cry skill erased.I did not understand how it is justice so we can only press R and waiting battle cry skill.Can you extend confusion skill colldown or another thing.For example when they are using confusion and our priest press cure skill battle cry can be come back.I want to say why when press confusion battle cry erased completely.For this case we can not play berserker warriors.
It is disadvanteges also erased 300 defense it is rule and very normal thing.But I dont understand confusion So berserker warrior is nothing Why we work will be reach 83 level.Please transmit it to game producer.

Note; Confusion skill is debuffer 15 lvl skill and it skill speciality decrease your enemys magic power by 30.
I could not understand why it is erasing Battle cry!
