DPS cooldowns

This term designates all short-time buffs which enhance a players or groups DPS output, and the use of which induces a relatively long cooldown.

These buffs include:
 * Heroism or Bloodlust
 * DPS enhancing Trinkets
 * many more

Significance
During most Boss fights, it's important for all damage dealers to know when to use these cooldowns. In some fights, it's important to save them until late (for example to beat a soft enrage), in others it may be good to use them early (to maximize early DPS), and sometimes, it's best to use them when the boss uses some random ability for the first time.
