Kotick earned that bonus, though, with all the good work he did this year on, uh...
Anyway, yeah. Blizzard churns talent. A lot of bright-eyed young graduates want to work there because they grew up with Blizzard games, and the company made a decision over a decade ago that rather than nurturing that talent they would work them half to death for half the going rate of their skill level in one of the most expensive zip codes in the country, then just casually replace them with a new graduating crop every year.
We're coming up on the point where those bad decisions will come home to roost, though. They could have used their legendary status to cultivate unparalleled talent and been virtually beyond reproach for generations, but instead they spent all that human capital on cash-ins and squandered their reputation. Graduates coming out of school in the coming years might know Blizzard as "those guys who made Overwatch, I think I played that in grade school" rather than the legendary studio whose games they grew up loving. They aren't going to get preferential hires anymore, and they haven't done a good job of retaining and developing existing talent to survive without the talent churn.
