Let me put it this way.
Game session of Star Wars RPG. Epic climactic fight. My brother's character is an athletic, heroic soldier. Really skilled. He is trying to reach the boss. Needs to run up stairs. Difficulty is 5 or higher. He gets +10.
Rolls a 1. Automatic failure, the rules said. He trips on the stairs. Everyone laughs. He's ticked, but he says, "Well. That's life sometimes I guess."
Next round, my unlucky brother rolls a 1 again. Trips and falls again like a blundering idiot. Now he's ticked that the rules say he has to keep rolling just to run up stairs. Also that it doesn't matter that he has +10 skill. When he needs to get to the boss who is butchering his team, because of some unlucky dice rolls, he is floundering like a moron on a staircase.
It sounds legit at first to allow for failure for mundane, simple skill checks, but in situations like this, players get annoyed and even ticked when they fail such overly simple checks. It's not worth the roll. After that event, I changed the rule myself, no longer forcing players to roll for difficulties beneath their skill.
So you're advocating for more homebrew rules?
