You are essentially talking about raids, but raids don't work in D3. There's no healers or tanks really, so as the monster damage goes up players start to die instantly. They really can't make hard encounters without healers and tanks. Every class is basically DPS. Sure you can get more survivability items so you can last longer, but I'm not sure Blizzard wants player to even worry about those different roles. I think they want every to be mainly DPS.
