Warlock or hunter, fear Roar. One tank tank Tito, one tin man. All dps on Dorthy with rogues kicking as much as they can. Mage on Strawman. If you don't have a warlock or hunter, or ones that suck, then one tank takes both Tito and Roar. BTW, if the tanks don't pick it up their targets fast enough, it is a hard fight to come back from.
