Forget library too many mobs turn back on big pulls. do cathedral and armoury.

enter instance
leave alts at entrance where they apear.
run sideways all the way round gathering mobs so you parry / block / dodge. (use strafe)

armoury - 1 pull all the way to herrods door. use DS 1/4 of the way back to heal so wings are rdy when u get back for DPS pull mobs to the entrance corridor to LOs casters and get alts in XP range.

Cath - 1 pull if your good geared 2 if not good gear. to do 1 pull gather all outisde doors get to doors, shield - open doors - tab boss and all mobs agro.
(jump off waterfall and u can get in 2-3 big heals before mobs runs round.)
kill in entrance corridor.

forget looting rinse and repeat. no need to move alts from entrance and they never agro or die.
