My first reaction:
Seriously, do we really need more pressure to repeat stuff, Blizzard? Do we really need more of the feeling "OMG I cannot take a week off since I would run behind everybody else!" ? Why do we have extended lockouts? We can't really not kill bosses, since we have to complete the quests! Right?!
My 10man is currently taking the time to get Firefighter on farm, work on Algalon, and Yogg+1. Can't do that anymore I guess or we'll not get the required items for our progression content. We can kill them easily on normal, so does this mean we should just not extend and get the items that will probably be required for progression content? Bah, Don't like this sort of pressure.
More later when I've thought some about it.
