Meh, on PTR today a pug group I was in full cleared ZA in 55 minutes. Bosses, trash, whatever were dropping like flies and the chests were a trivial matter. I think we got the fourth chest with over 20 minutes remaining on the timer. By the way, you get 2 ring drops now, so it goes armor>weapon>ring>ring. This was a full pug mind you, none of the 10 people in the raid knew eachother prior and we picked up members through tells in trade chat. On top of that, our second healer dc'd right after hex lord so we did zul'jin with 1 healer, both were resto druids.

On that note, a pug Gruul I was in repeatedly got face rolled by high king and his cronies in about 30 seconds per attempt, for some odd reason some of the retards in the raid failed to let the mage make the pull.

So, you still have to know the fights and do what your supposed to, but the fights when done correctly are a cake walk.
