Since it was added I have only had a raid extended once, back in cata. So I don't remember how it works, and googling it didn't help. lol
My raid is saved up to heroic Nazgrim. tonights raid was cancelled and the officer said they were saving the lock. Now I'm sure this means extending it. My question is can I find a pug and finish the rest of the raid tonight and still be able to join my group tomorrow at Nazgrim?
