A common misconception about the CSM is that you can run on a specific platform, get elected on that specific platform and then be successful in changing things. My term on CSM is not an accurate representation of how things normally work. I was successful in totally reforming the CSM because reform was already in the cards. I was the only reform candidate in history and I got elected during a time when there was already crazy pressure on CCP to reform the CSM.
If you are the “War decs are broken” candidate and you run successfully on that “platform”, great job. Now what? You ran on something common sense and got the vote out but this year CCP isn’t iterating on that area of the game. So your all thumbs during CSM meetings.
Running people from a given play-style of the game is by itself not enough. The person needs to be polymathic and intelligent outside the area of their focus. The concept you laid out won’t work for something like the CSM. It would be a waste of seats for people that are generalized in their focus or narrow to a region or playstyle.
