Pros
Every company is made up of its people, and the people at Blizzard are well worth staying for. It's a place where the core values ring true for most people in their daily lives, not just in corporate meetings. Different teams have different cultures. but mine has been the right blend of laid-back but with keen interest in equity and improvement.
Cons
A|B has had its struggles, largely in leadership communication and oversight. This has lead to some teams taking on a less healthy or welcoming culture, and also in a certain bureaucratic slowdown in progress which leads to lengthy times between promotion cycles and shortfalls in pay increases as the company struggles to keep up with rapid changes in economy. As with all tradeoffs, this sluggishness provides a certain stability, even if it comes at the cost of personal economic or career growth.
