This zone is boxable with average Velious geared tank and healer. I boxed it with a berserker (307aa) and a mystic (211aa). It was not not hard. The only mob that you have to manage your mana is Riyadh. In addition to this: mana is not the problem: Riyadh silences you and strips you of your buffs. Also summons 5 treant adds and seems invulnerable as long as those are up.
