They are quite evidently not the only form of game progression.

So you're asking that no one criticize your idea, and saying you only want comments from people who support your idea. In other words, gatekeeping your own thread! Furthermore calling this a need is a pretty strong word. No one is stopping you from playing with your friends. In my experience, friends are always willing to play with you at whatever level will work best for everyone. This change would cause more problems (communication complications, poor team composition resulting in dissolved teams and hard feelings or worse, alienation of new and returning players) than it would 'fix' (none).
