I do all the time. Every patch I have a look at a guide to see if something's changed and there's something obviously stupid about my talents. Then I look at what's the best and if it's something I don't like doing and there's something not quite so powerful but still ok that I like, then I choose that.
At the casual end of playing, 2% of dps is only 200 dps. Who fucking cares. You get way more dps by actually playing something you are comfortable with well.
