AK is hardly hard... in fact the only time I've had a group die to the demon walls was the first day, we went in again all getting ready for a super DPS check just to find that it didn't even reset everything.... just gave us the time but left us with only three mobs. Very nice of it, actually.

Not to mention you can still attack while being trapped in the jelly during Ferdiad. Ranged = no problem.
