ICC progressively released
Correct me if I'm wrong but if my memory serves me right, ICC was released in tiers. Referring to the achievemenents I believe it was like this: Storming the Citadel, Plagueworks, Crimson Hall, Frozen Halls and finally the Lick King, wing by wing. I'm not sure about the timeline on each one of them induvidially or if they ever released two wings in pairs (Frozen Halls + Lich King etc.). Either way, I personally think it just sounds like a nag instead of some kind of heroic anticipation prior to each wing release, I just don't feel it. If it indeed was released in this gradual manner when WotLK was live, are we to expect it to be the same here? I personally feel it will be prolixly and dull since we already know what to expect.
