Read the article and am not surprised that Warhammer Online is going down.
I had started following the progress of the game well before it was released. When Mythic started getting closer to the original release date for the game, they started to announce there would be delays and soon it was revealed that the reason for the delays was that EA had purchased the company. The programming team stated with access to more resources and other tools they were going back to retool some of the features. At the time, I thought this would be a good thing.
I got to try out some of the beta, and it seemed neat, but I was concerned by the fact that some of the factions still were missing class details and screenshots. I missed getting into the game at launch but learned that at least one race was released without one if not two classes actually completed. Several friends of mine had played it for a while before I gave it a shot and though it was a nice change from WoW, I was somewhat disappointed at what I experienced; despite it having had several patches and updates, it appeared that Mythic (despite the resources made available by EA) had failed to come close to delivering on what they had promised in all the release notes leading up to the game going live.
I did go back to it, about a year or so ago (around when it was free-to-play up to lvl 10) and it still lacked something...even subbing for six months, the game had a very "unfinished" feel to it which is a shame cause I've always liked the Warhammer Fantasy setting and had hoped the game would live up to expectations.
Like I said, I'm not surprised it was failing and now being shut down. Partly because every MMO that has been released after WoW that took on the mantle of "the game to dethrone WoW" have failed; whether this is a cry from the player-verse or the company itself, the results are the same, they line up against WoW and can't deliver. A few years ago, I read an article where an analyst was asked about what a company would need to go up against WoW and the answer was a minimum investment of around $2 billion into development. I don't know how much time and money was put into Warhammer, but it was not a WoW-killer. The second reason I'm not surprised it is shutting down is: EA. Lately, EA seems to be the kiss of death to many potentially great games and software companies.
