this is all assuming the tank pull 6+ enemy in one go

should i just quick nock non stop or apply both poison debuff on every each enemy? quick nock is simple and easy, this is what i usually do.

someone in my party suggest me to put both debuff on every enemy, when i try it the enemy already dying by the time i finish putting all the debuff thus i feel like iam doing nothing, and by that time the previous debuff is already out too so i need to reapply it again.

which one yield more dps in aoe situation? can someone help?
