Seems like they understood it perfectly. Being a leader means being the one who supports the team and pushes them to get the most out of them, whether its through mentoring, empowering, helping to fix problems or just generally keeping up morale. A leader is always one in a team and never, ever above any other member of that team or the team as a whole.
'Director' on the other hand is a completely different story; that's the guy with the vision who tends to make final decisions, but I haven't seen anything to suggest that the directorship for WoW is changing.
You do understand the principal behind cooking? The first rule of being a good cook is to always taste your food. Literally one of the first rules they teach you as a chef, which is something that Chef Ramsay constantly says. While taste is a subjective thing, generally if something tastes decent to you, it won't taste awful to most people. Now with that logic, if you eat a lot of cookies...I'm sure you can tell a good cookie from a bad one. Now just because you don't like, say, oatmeal raisin doesn't mean that all oatmeal raisin cookies are disgusting. And that's important to understand. Which I totally do.
Nothing I said implied that I thought I was "the best chef in the world" or rather, the best player in the world.
I'm saying that as someone with experience actually playing video games, I think I know enough to start the ball rolling and add new fun elements to the game. Experience is everything.
That's the thing. Experience isn't everything. Reinforcement principles (objective) play a much larger role in directing behavior than how "enjoyable" an experience is to any one person (subjective). That is a pretty important, and basic, item to understand.
