So, I play with my kids and when we do dungeon runs, I multibox the Warrior and 2 Mistweavers.
When they aren't playing, I of course run the whole group through LFD by myself.
They are still in their 20s, but, this composition is a lot of fun as far as I've seen.

The Mistweavers DPS when they aren't healing. I'm running ISBoxer's VideFX for the healer click bars so it's extremely easy to heal so far.

Has anyone tried this composition at high levels?
Any gotchas?

Thanks!
