OP, I want that too, but I feel like the player base isn't ready for it.
I feel like what we need are more tools in game for helping the player improve.
When I started I played for about a year before I realized everything I was doing as SMN was wrong, the game had never really taught me how to play, and I had so much unlearning to do I just ditched the class (despite how much I liked it). As it stands there's still very little to tell a player that they're doing well beyond "did you die?" And if they had more tools in game to help people improve the community would be better prepared for harder content.
As it stands the average player is just... too not good.
