IMO Blizzard is becoming lazy without Activision. From the late 90's early 00's they cared for their merchandise. I believe blizz just felt wow classic gold overly powerful regardless of activision and believe people will play with the game no matter. You never wanna blame for the company who had a significant part in your youth (Halo for Bungie and Warcraft/Starcraft/diablo for Blizzard) but acti. Still has good games that people love.I don't know whether I would point to some one important"thing", although obviously the Activision merge is one of the largest ones.
But I think you are correct in they became complacent and also forgot what made them popular to begin with. Look at Diablo 3's launch, the lead guy working on it had open disdain for its prior director, there was this haughty feeling to the total layout and release that everyone would play with it just depending on the title.It's a shame, but it's the nature of the games business too.
Companies come and go for a variety of reasons. Blizzard will either sort itself out or fade off.If there is something that's been consistent about wow forms from 2004 to today is non-stop complaining and raging.The 2 things I hated about WOTLK was the return of Naxx along with the Argent tourney. Paying for rehashed content felt pretty fucking bad. Especially since it was the very first raid after falling cash for the Xpac. And the argent tourney had the absolutely worst dailies ever and then a"raid" that you just sat in 1 shitty looking dirt floored space for 90 percent of it.I think having Naxx was nice.
But it being the very first thing that you encounter was just kinda meh timing. But anyhow they made up for it with Ulduar.Ulduar was the ideal raid Blizzard ever produced and it had been so quickly made irrelevant from the worst raid Blizzard ever made. It's mind boggling.It felt bizarre to cancel my sub shortly after having the most enjoyable from the game I have ever had. Blizzard said they made the cheap classic wow gold Argent tourney raid because Ulduar took too many man hours and dollars (it truly was epic, so lots of bosses, so many rooms, almost every battle made nicely )... like, a stunt worthy of a multi billion dollar company.
