Calming Rooms in HS

[Barlu]

I recently come back after a long break and been messing around with my 57 Enchanter in HS. I have been doing mostly North so far and have been having some issues with Calm. I seem to remember if you calm 3 out of the 4 mobs in the first room down the stairs on your left you could pet pull or pull the 4th single with Tash.

Since I’ve come back, I have Calmed 3 of the mobs in the room and attempted to pull the 4th and get multiples almost every time. Has the agro radius on Calm been reduced or am I doing something wrong? I seem to recall both pet pulling or Tash being able to grab singles with everything calmed. I definitely don’t think it’s a time thing either. I’ve calmed them all with only 2-3 resists before trying to pull and still getting adds.

Anyone know what I might be doing wrong? Thank you all for the help.
