5boxing is slower than running 1 single character but way faster than leveling 5 characters solo...

In general I skipped all the looting/gather quests and mainly did kill quests or FedEx type quests or grinded mobs (preferably ones that dropped cloth)... Right now the toon I am running in the foreground is my main aggro character that has first priority on gear and I filled that character's bag slots to give him as large an inventory as possible and for now I set loot on "Free for All". I also made that main lead my skinner as I am skinning way more than gathering or mining...

So far it has been working pretty well with the above approach as I really only loot on one character most of the time. I suspect once I start running dungeons and start receiving Bind on Pickup (BoP) gear I may need to change to Master Looter or something so I can make sure the right characters get the right BoP items...

In general I like the challenge of multiboxing and being able to gear my characters in at least pre-raid BiS at my own speed and preferences.

I do also hope that it ends up being very profitable to funnel gold into my main(s).
