That is a pretty cynical view. Most people who lead raids do it to help the community run content where there is a desire but maybe not the experience to run it themselves. Not exactly selfish control freaks. Sure, people who do the same raid every day know what to do without instructions, but raids need to provide basic instructions for people who don’t do them all the time. It only takes one person who doesn’t know what to do to make it go south.
Out of curiosity have you run any iTrials, MSR, or Hamidon raids?
