We've had a few groups of warlocks and some number of healers/tanks around. Sounds like a good mix. Do some searches and you should find what you're after. Note that the built-in search function tends to suck. In lieu of that, try this:

Go to google and search for "site:dual-boxing.com <searchword> <searchword2> <etc.>"

That should get you much better results.

And welcome aboard!
