Cleric friends, teach me how to paci/atone

[RobotGraveyard]

Hello! Level 55 cleric here. I have been gradually learning how to use paci/atone now that I am grouping more. I decided to test it out with my goal being to paci/atone my way through the entrance of The Hole. I have no issues with paci, I got lucky with my 128 cha and managed to paci all but 1 of the entrance mobs. I figured this was perfect to try to atone. Nope. Train. Did this 5 or 6 times and then logged to an alt.
My method that didn't work:
Root -> atone (clickie staff) -> paci
Always got attacked, always drew agro from the neighboring mobs that should've been paci'd. What am I doing wrong?
