Leveling Strategy?

[Feedcoma]

I am planning to get a team of 15-20 accounts. How should I level them?

Maybe 5 at a time in a party?

Or maybe 20 at time in 4 parties, doing each quest a few times for each of the parties?

From your guys' experience, what do you think is the fastest way to get a large number of characters to max level?

(I'm on Icecrown btw.)

Multiple groups of 5 played simultaneously imo.

Alright, I'll try that way.
