Our guild has only downed 1 boss in the Firelands, and it is only one of our raid teams. This left the only options for our raiders to have to run ZA/ZG ad nauseum. (My guild is the kind of guild this change helps the most, and there are a great many guild's like this).
I'm glad to have this as another option for our guild's raiders to save them from burnout from having to somewhere dig up another 10+ hours from their personal lives to spam farm these things, especially across multiple toons.
And as a guild leader who has limited time due to many work hours, and much of the rest of it spent with my guild, thank you very much.
