"or do you still think "most of the people in charge of making the game" equates to Bill Roper, the Blizzard North founders, and a small handful of artists and programmers out of several hundred employees that have worked at Blizzard? "
Quite frankly, yes.
Everyone knows it is always a handful of special people who do something and everyone else is a "hanger on" or "worker".
Blizzard North were the special people. The ones still there were the groupies.
You know how you tell? The good ones have the confidence to leave when evil takes over the corporation. The rest of them know they don't have what it takes.
