I think the big thing Blizzard is trying to do is to get people to synergize with other characters in a party. So yes while ur tanky melee hero might have a hard time being constantly feared away the idea is that he (or she) is the distraction while some ranged dps or spell caster nukes the crap out of the masses.
I think its silly to have a melee class be a distraction while the ranged gets to be safe and do all the dps. I as a monk should not be running around like a headless chicken while someone else standing at a distance is doing dps.
I don't believe that the intention is for that type of play. It's supposed to be a symmetry of skills coming together to maximize dps and survive-ability.
