In case you didn't know currently there is an event on the PTR where Deathwing informs you that you can now face him in the Dragon Soul Raid. He visits Orgrimmar and Stormwind and sets it aflame. Now from a lore stand point I am not sure I like this. Since Orgrimmar had to be rebuilt when the fire elementals attacked and set the city on fire. But now Deathwing is going to set it on fire and it will just disappear and everyone will be on their merry way. So from that stand point I don't particularly like it, but there is a lot of in game mechanics that lore was don't make much sense so I guess I can live with it.
The thing to remember though is this would all but guarantee everyone would get the feat of strength for getting hit by Deathwing because who isn't standing around in Orgrimmar or Stormwind? Now this kind of makes the feat of strength less awesome, but it never really was more than just luck anyway. So the people who some how are hated by RNG so much will finally get whats coming to them, a pissed off dragon is going to flyby and murder them.
Another thing to note is this could just be a PTR thing, but only time will tell if that is the case. Here is a couple videos of the event happening in either city
