Oh Snap :
Because they hyped it up and used the Diablo name to push a game that was nowhere near anything Blizzard has made. They promised a bunch of features that weren't released. Plus, everyone basically bought a $50 **** demo unless they were willing to spend more money for something that was provided for free in just about every other multiplayer game.
Are you new to the video game world? As you must have started playing wow like at max a year ago. Blizzard has done everything you ranted about Flagship doing and more. WoW was hyped as a PvP game where on PvP servers we would be able to to sack cities... You obviously never played WoW during launch as the server issues were horrible... Every Server could only be up 50% or less a day and even when servers were up players had to deal with Roll backs. The Roll backs were so bad it would take people days to get beyond lvl 10....
Oh and lets talk about Server issues like on PvP servers how the PvP servers used to crash daily when horde and alliance guilds would clash. You get over a 25 vs 25 and the world server was ready to explode...
WoW also promised many features PvP wise that have never been implemented or now are getting implemented about what... 4 years later.... The only two implementation of 1 thing they promised was Halaa... a capturable town and the upcoming Wrath of the Lich King pvp zone in rend....
Oh Snap :
It wasn't just another **** independent release, it was a **** "HEY LOOK WE'RE THE SAME PEOPLE THAT MADE DIABLO SO THIS GAME IS GOING TO BE EPIC" independent release that got everyone's hopes up with empty promises and dashed them to pieces just shortly after that $50 was unrecoverable.
SO your saying buying WoW which was a giant hunk of crap upon release and was dubbed "WORLD OF WAITING" because of issues like SERVER QUEUES which had people waiting up two 3 hours to get in game was an excusable loss because only a year later were they able to fix the games issues?
Fact is of any company that got away of releasing a giant hunk of **** it is Blizzard... They promised the moon with WoW and only delivered on about 35% on their promises. PvP in that game is still Terrible and in fact worse then before. The BGs ruined World PvP, Arenas is so poorly made and is one of the stupidest ideas for an MMO, the PvP is so imbalanced that when you arena you know if you are gonna win or lose just by seeing the class composition of the opposing team, the quests are still uninspired and boring, and what real reason is their to play that game if you can't get into a raiding Guild?
You realize that even Blizzard stated that most of its player base will never see HIGH END CONTENT? The casual player base of that game have no reason to lvl to 70 as the only real thing they will ever do is Kara....
Please before you are gonna talk about companies saying their product is crap don't use Blizzard to justify your argument. The only reason WoW is around is not due to being a good MMO... (it is one of the worst) but due to its name.. Warcraft was awesome so people think WoW is gonna be awesome. If WoW was stripped of that past and was released by say PlayNC EQ2 would still be the game of choice....
