Was great! Not any more.
I specifically disliked when they added features like dungeon finder, and even raid finder! Those were disasters! All the mysterious part of the game was washed away. That was what I particularly liked about World of Warcraft. I lived it, but now I have to only play it!
I haven't bothered playing Mists of Panderia because I don't like the idea at all. It is not relevant to Warcraft. But from what my brother says (who still plays), the boredom factor hasn't changed.
