That's where I think most people are wrong about inferno though. That difficulty rewards proper communication and group play. Sure, soloing everything requires a crap-ton of godly loot, but damage and defenses can be compensated by a proper synergy of group skills. Lack armor and resists? that Barb shout may just solve it. Your tank getting face-melted a lot? You could have a monk stack a 50% damage reduction debuff on the enemy. Your glass cannon wizard getting chased down? Have a witch doctor load up on CC skills. What I'm seeing everybody try to do is to gear up and go berserker on the enemy and it just doesn't work.
