But something happened after the success of WoW the company grew quickly and with that came some bad people and after the merger, Bobby Kotick could exert his influence.
Blizzard stopped being a geeky place for geeks and culture eroded slowly.
I also believe that the original core Blizzard people were struggling with leaving the company in the hands of the next generation. They wanted to believe that the people they had in the company would carry the torch and embody the same ideals. It didn't happen.
The saddest day was when Metzen announced his departure. It was felt by many as a shock. He was a beacon of hope and light but I also think the was struggling with some personal family matters. He now felt the work was no longer in his best interest and left. A lot of Blizzard veterans followed suit. I don't think a single one of the original people still work there, with the exception of Samwise Didier. Blizzard still has a very strong art department.
I believe Michael Morhaime did what he could but ultimately realized that he didn't have the autonomy to fix it. The problem had grown to big. Maybe they were naive? I mean, these people struck gold and built one of worlds most renown gaming brands and the worlds most successful MMO to date.
On the flip side. All the key people have moved on to found new gaming ventures and I believe this time they've had the capital to fund it themselves. Hoping they stay independent and build great experiences for us to enjoy.
