Not exactly what you're asking, but for perspective, I took a 5-box mixed team from 0 to 80 in 4 days played time using only RDF.

My thread is here: http://www.dual-boxing.com/threads/4...y-armour-types

This involved a lot of learning on my part, for ISBoxer, multiboxing in general, WoW to a large extent (I had never been in a dungeon before, for example.)

It would probably take you longer to get the 85 setup and heirlooms than that, I'd guess...

The only leg-up I gave myself was 1k gold from another account and even that isn't strictly necessary, imo.
