i suggest using the 'move to mouse click spot' mechanism so you can instruct pally #1 (P1) to a spot and while he is running to it... with his mages in tow... you could click P2 to do the same... repeat for all pallies.

then, hit consecrate and arcane exp to all toons at once across all 5 instances. keep arc exp until all dead. scan around looking for anyone that needs healing. then loot.

once you empty the instance, walk out, reset and repeat.

good for xp and loot
