Apparently on the 3.2 PTR you will be able to extend the lockout period for raids. Find more over at wow.com.
My first thought is...
Our 10 man progression group runs once a week for three hours. That is it. Even then we take weeks off. Currently we are in our fourth week of "break" from progression.
In Ulduar we have killed Flame Leviathan, Ignis, Razorscale, XT-002, Assembly of Iron, Kologarn, Auriaya, and Thorim. Before our current break we got a good look at Freya.
Killing those eight bosses takes up most of our one night of progression. Eight bosses in three hours is quite good I feel. But it would be great to get a full night with Freya and Hodir.
This change is something for raid leaders to look into and use.
Thank you Ratter for pointing this out to me.
