Start using Old Spice. I saw on TV that it puts hair on your chest. Get your brother to do the same and he wont be scared of Heroics. Movie theme music might help and stream Braveheart on another box for a morale boost too.

/target tank
/cast healspell

/target shaman
/cast AOE Heal

That should get you started. Its not any different than setting up what you already have if you are 4 boxing a paladin and 3 shaman.
