Ok Terribad, I can see the point you bring.
How about this; if a "casual/bad" is "scared of colors" in game, as in the player has found through leveling and story progression and open-world regular mob killing that he's only hitting 'Orange Level' at best.
Next step would be: "How does this player get the resource available to improve himself, within the confines of the game? How do they improve their skill, while being engaged in the game?"
How about this; you setup an NPC for your Job which is scripted to encourage you with tips and tricks on a dummy beside you, telling you which buttons to press on your bars (like Dance Dance Revolution style), telling the player to keep up with him, encouraging the player to get better. You could make that NPC anything really, which would work Lore-wise, such as your inner-self giving you pointers on self-improvement.
That way, it provides the players with a means to knowing if they need to improve, and an in-game tool to improve their button pressing abilities.
I think that would improve on the problem, don't you think?
