The first 3 groups (+ 1 roaming shark) can be a very difficult pull especially if either the tank or healer don’t know what they are doing.

If one of them doesn’t know then it’s usually a wipe.

That being said, if either are not comfortable with wall to wall pulling the they should just pull the first two groups plus add then last group, as it takes more time to wipe than it does to do the two groups separately.

“Well how do I know if my tank or healer isn’t comfortable?”

Easy, you ask them.
