Based on your skill choices and the way that you are dealing your damage you may not need as much Fury as you think. Personally, most of my damage output comes from Cleave and I seldomly am spending fury anyway. However, if you find that your Fury is frequently low there are ways to beef up the generation. There are several runestones that help fury re-generation. Your bread and butter Fury generation is obviously going to come from your Fury Generating skills.
