I 10-box this place and certainly have more than enough CC to do the whole area up to the first boss.

What I've found - not worth it. It is so unbelievably fast to kill 3 out of the first four, exit, and re-enter. Never wipe, never lose a toon, never wait for pathing groups that are too close to each other. I've done it both ways plenty of times and I have to side with Pinot.
