It seems like your complaint is really about the players, and not Captain's Mode itself. You can't say that Captain's Mode is 'imbalanced' simply because players don't know how to draft, pick or communicate with their teammates. There is a reason you can select what mode you want to queue in. If you don't have a stack, it's unwise to queue Captain's mode because you likely wont have the same communication to get a good team compilation and wont have the knowledge of your teammates skill/heroes they are skillful at to make educated choices as a captain.
Does this mean the mode is 'unfair' for lower level players? Technically, you could suggest it isn't fair, because lower level players wouldn't have the overall hero knowledge or ability to adapt that higher level players would. The issue is, that this is not the game mode's fault, it is the fault of the players for queuing in a mode they are unlikely to have the game knowledge to play correctly. You can't blame a mode when people have the option to simply not queue in it.
You could say the same for AR and SD though, since these modes essentially rely on players to have good overall knowledge of the heroes in the game; therefore these modes suffer from basically the same issue as Captain's Mode - lack of knowledge on the players' part. They are more 'unfair' though, because you can't work around that, by picking heroes players are comfortable with and banning others like you can in CM.
I feel like your argument hinges on the player base and not the mode itself and calling CM 'imbalanced' because players don't know how to play it is a fallacy.
