I started working on this zone over the weekend.

Trash really worked on my CC skills, wasn't able to get by the first named (though only tried about 4 times).

First question is on CC.
I have key binds so I can set each dps focus target, then one key that will do the CC (sheep, hex, banish). For this zone I was using 2 hexes and 2 banish.

I would get my focus targets, then run up and pull with the tank, run back (sometimes using line of sight to bring everyone in), then spam the cc skill a couple times as the mobs came in range (got around corner etc.)
This seemed to work okay but didn't seem super elegant, kind of messy at times, as the mobs would be CC'd and meandering around my team.

How do others do this?

Finally on the first named, I would do okay, adds would come round them up fine, but then suddenly my tanks hitpoints would just drain out, at first I thought it was just the debuff the boss puts on the tank, but seemed something else was going on, I just couldn't keep the tank up, even when sending heals from my shaman as well.

I did some reading and I read something about the malignant trogg that needs to be CC'd or I guess not killed at any rate (sounded like he had a debuff too, or maybe it was boss gets dmg buff if he dies).

At any rate it seemed something else was going on, but from this thread it sounds like there wasn't anything special about the fight (other than avoiding his charge).

Do folks just leave up all the adds beating on the tank? I thought I read if you don't kill the malignant one more adds won't spawn...
