Later on when you want to reach higher damage, its actually really important NOT to use your Tiger Brew instantly at 10 stacks, but also never hitting 20 stacks. You should always try and set it up together with some of your cooldowns or with some kind of burst, just like brt2pp said, if possible. But one thing you should ALWAYS do is use it together with Fists of Fury, doing this will increase your damage significantly (when you channel FoF you will also pool some energy for additional burst).
