DPS race

From WoWWiki

In some boss fights it is important to quickly kill the boss before he kills the raid. This type of fight is called DPS race, and usually has the following characteristics:

• Some effect guarantees a wipe if the encounter takes too long (for example some periodic effect which kills players or an unusually short enrage timer).
• In principle tank and spank (no difficult positioning or evasion needed).
• Not aggro capped (for example because the boss only attacks targets in melee range).

Example: Moroes, Kaz'rogal

With good enough gear, DPS races degenerate into tank and spank (derogatory form).
