Well, first of all, as a long time WAR player, I blame EA. Fire most of the staff immediately after launch: check. Cut funding to near 0, so that even bug fixes come slow: Check. Constantly reshuffle executives in charge so that there's no clear goals: check.
As far as WoW/WAR goes: WAR couldn't help but be somewhat like WoW. Since the original Warcraft was a re-titled Warhammer game when SSI and not Blizzard got the rights. Blizz was left holding the bag, since they had gone ahead with development before they had actually acquired the rights, and the game was all but finished. Some quick changes and voila! Warcraft.
I might point out that shortly after WAR launched, WoW suddenly sprouted quite a few WAR-like features as well, since Blizz was actually concerned about losing players to WAR. They of course, had not counted on EA shooting the game in the head once they acquired it, instead of running it in a sensible manner. It seems to only recently have occurred to them, now rather after the fact, that the property might be/have been profitable after all, with all the hype surrounding the 40k MMO.
