MMORPG wrote a review in progress and now it's finished. All three parts are pretty interesting and if you want to get more deeply into the expansion and what it provides to the players then read
Suzie Ford summaries and evaluates the expansion in words:
I want there to be no mistake here: I love Warlords. I love the new things, the new features, the altered skills, all of it. I don't see myself leaving any time soon. But I am also pragmatic enough to realize that, while there is so much more to discover and enjoy now that I've reached the level cap, I am still left with that nagging feeling that it will all become old too soon for most. Blizzard is going have to keep their word to release new content, expansions even, at a much quicker pace than before. Otherwise, even stalwart diehard WoW players like me will start to grow weary and wander off in search of something new.
