I think there's a lot to be said for letting naturally gifted players keep doing as many of the things that have made them such a talent as possible. I'm not a fan of modifying successful bowling actions to make them look better, or trying to make batsmen who score runs playing across the line stop doing it. As with anything, it's about moderation I think. Without sounding like a motivational poster on an office wall, one of the things I always tried to do as a coach was to improve the mental part of the game. If you're a batsman with the shots in your armoury to score runs, then identifying the right situations to use those shots would be my focus, not working too much on the technical aspects of it. I think there is very much a tendency to overwork the latter, and 'coach things out' of players rather than just improving the way they think about the game.
