This game is designed so weird for endgame. Every single game I have played in act 2-3-4 in inferno has been: after you meet your first elite, just run until you die, everyone revives at the body of whoever managed to run the farthest, run with all the mobs chasing you very much like in the youtube video trying to gain some more ground, rinse and repeat until you get the objective done. Then corpse-hop through the next instance. And the next.
