Instead of playing a role almost everybody is trying to make "efficient" "overpowered" characters as if it was some sort of a competition which you can win.

I typically play storytelling games (like Dread) in order to get the story as uncontaminated by tactics as possible.

It would be the DMs job to match difficulty level to our characters, not the other way around.

This simply does not work. The issue is matching the players to each other, not the difficulty to the characters. The three primary dimensions are time spent talking vs. fighting, plot vs. autonomy, and competence. Mismatch between the players on any dimension will cause conflicts. It's everyone's responsibility to form a group with accord on desires, and then the DM's responsibility to deliver sessions that line up with their desires.
