First than all, yes, I feel like a newbie as I ask this. Second, I had some issues to hold eminty with the slugs, because my healers always pull those adds as I flash (carefully) the said monsters. I say carefully because of the jellies. The way I do it is: when they spawn I use flash, then I stack with the group and keep flashing until acid rain. When acid rain occurs and having the slugs away, I keep flashing until the super slug appears. During that phase and prior to that phase, I usually lose aggro from one or both slugs. Any advice here?

In my static I have a WHM and a SCH. It's usually the WHM the one pulling the slugs.

Thanks in advance.
