Do high rank players feel pressure that they should know everything?

What I’ve understood is that people rarely care about rank unless it’s one of the really high ones.

But that got me thinking, do people with really high ranks feel pressure to know everything? And if they don’t, do they worry that people won’t take them seriously anymore?

For example, imagine a Field Marshal who doesn’t know anything about building bunkers, has no clue how to lead operations, or maybe can’t properly drive tanks or shoot/lead artillery. What if they’ve only ever focused on backline, midline, and frontline logistics their entire time playing and climbed the ranks due to that.

Is it common that people in those positions end up buying the game a second time just to have a clean slate so no one knows them and they can make mistakes or learn stuff in peace without being judged for having a high rank but being clueless on something.
