Glad it helps guys, I haven't tried it with more than one yet as I was just finishing off a couple of characters on my healer account. But tomorrow I'm activating everyone and filling out their rosters.

Instant damage abilities work best obviously, like lock/priest dots and Crane Kick. But that brings me to one of the more difficult situations, it's easy to get wrecked on a lowbie melee if you're not super careful. Early hours when there's only a couple of people on are safest with a ranged I found. I'm still experimenting, so if I find anything significant to share, I'll be back here asap. I'm not sure that they won't nerf it, but it's working enough to get my last healer up and maybe a few others. I got a Warlock to 60 this morning while I had my coffee, so yeah... It's pretty silly.

If you're sitting on Elixir's of the Rapid Mind consider either using them to burn through or get some gold out of them while you can.
