with 15 accounts, 10 hunters and 1 healer with 4 toons just to /dance and /laugh at opponents will be sufficient!

Seriously, though. I used to run 4 hunters, 4 DKs and a paladin + priest healer.. it was ridonkulous. I can imagine that 10 hunters and 5 druid healers will be unstoppable. I actually have a plan to write about this setup (with up to 10) soon in my team thread.
