I just started a 4 mage team to catch up to my decently geared 80 mage, and I"m in cath at the moment, the lowbies are 25 now. It takes me 4 to 5 minutes to do a cath run, and that includes an evocation at the door to the cathedral. 22 minutes very slow, even for a crappily geared 80. Park your guys at the entrance, pull the entire courtyard (spamming arcane exp and ice lance, usually) and AoE all the courtyard down, move your guys to the door of the cathedral, drop your mirror image and elemental right in the middle of the room, ice lance Mograine, and AoE the entire chapel. Sleep, kill Whitemane and Mograine, rinse, repeat. 10 minutes tops if you have to eat/drink.
