We seem to have missed a review of Warhammer Online: Age of Reckoning that was posted on Gamer's Hell earlier this month. This conclusion sums up why the game received an 8.5/10:
Overall, Warhammer Online: Age of Reckoning is a well balanced and fun MMO, that has had one of the smoothest launches to date. With only two months under its belt, Mythic has already announced plans to address most of the issues I've mentioned with their 1.1 patch that is slated to hit in December (which also includes the addition of two classes that had been cut previous to launch). If Mythic continues to be this responsive to the needs of their subscribers, this game has a lot of potential. The MMO market is not a friendly one, and whether a more casual friendly, RvR focused MMO will have the longevity of other successful MMOs is hard to judge.
