What do you think about running Cata Instances blind,without any knowledge of the bosses? I usually run them with my guild which everyone is on vent,so It's easy to tell people things they need to know,if they don't exactly know the bosses,but if people pug for the instances which people aren't on vent,is it a good idea to research the instance first,as it'd be easy on the group,if things don't have to be explained beforehand,but if people want to come into the dungeon blind,so as to better experience the content in said dungeom,so to speak.
