So basically: people are sick and tired of anything that instanced. And here they have a chance to break away from the boring daily queuing for another ID that locks you out for another 15-30 minutes.

Mob Hunt doesn't ruin the game, it just shows what people wanted all this time, the open world content that is worth your time.

P.S I have to agree though, that the Elite Marks should be tougher and make more window for other players to participate
